Abstract:
Rubidium atomic frequency standard (RAFS) is the most widely used frequency standard in space. The light used to pump the atoms and detect the resonance signal is emitted by rubidium spectrum lamp, so the light intensity of rubidium spectrum lamp directly determines the performance of RAFS. This paper discussed on-board RAFS’ output frequency fluctuations caused by rubidium spectrum lamp. The reason of frequency fluctuations from rubidium lamps was described. To obtain stable lamp light intensity, analysis and optimization of the lamp was developed. Relevant experiments were carried out to verify the optimization. The study content of this paper is beneficial to improve the performance of a single temperature controlled space RAFS physics package.

Abstract:
A common voltage-controlled oscillator (VCO) architecture used in the phase locked loop (PLL) is the ring oscillator (RO). RO consist of number of inverters cascaded together as the input of the first stage connected to the output of the last stage. It is important to design the RO to be work at desired frequency depend on application with low power consumption. This paper presents a review the performance evaluation of different delay cell topologies the implemented in the ring oscillator. The various topologies analyzed includes current starved delay cell, differential delay cell and current follower cell. Performance evaluation includes frequency range, frequency stability, phase noise and power consumption had been reviewed and comparison of different topologies has been discussed. It is observed that starved current delay cell have lower power consumption and the different of the frequency range is small as compared to other type of delay cell.

Abstract:
For the frequency detection by using chaotic oscillator, in this paper, the results which are under the influence of the sampling frequency on the basis of theory that the output variance of the system will reach a maximum when the reference frequency equals to the signal frequency are analyzed. Experiments have indicated that the accuracy rate of the results will be improved and the signal to noise ratio (SNR) threshold will be reduced by increasing the sampling frequency to a certain degree. Besides, we have a further research on detecting the frequency of a signal with an initial phase based on the theory mentioned above, simulation experimental results have verified the output variance still has a drastic change when the reference frequency is equal to the signal frequency.

Abstract:
Physics package is the core of rubidium atomic frequency standards (RAFS). In this paper, a physics package of RAFS with enhanced performance is reported. The physics package is designed according to the separated filter scheme, in which an optical filter and a magnetron microwave cavity are used to reduce the white frequency noise and to intensify the resonance signal. The light-shift (LS) and temperature coefficient (TC) can be conveniently adjusted in the separated filter scheme. A preliminary test shows that a frequency stability of the RAFS is less than .

Abstract:
碩士<br>國立臺灣科技大學<br>電子工程系<br>100<br>First, this thesis presents a novel complementary low phase noise differential CMOS Hartley voltage-controlled oscillator (VCO), which uses only the supply voltage and the tuning voltage as the biases. The low noise CMOS VCO has been implemented with the TSMC 0.18 um 1P6M polycide CMOS technology. The VCO operates from 5.49 GHz to 6.29 GHz with 13.58 % tuning range. The measured phase noise at 1-MHz offset is -118.42 dBc/Hz at 5.65 GHz. The power consumption of the VCO core is 1.694 mW. The VCO occupies a chip area of 0.529 ×0.674 mm2 and provides a figure of merit of -191.09 dBc/Hz. At the supply voltage of 1.1V, the core current of 1.54 mA, the core power consumption is 1.694 mW. Secondly, we introduce the operation principle and design of a novel differential dual-resonance divide-by-3 injection-locked frequency divider (ILFD). The dual-resonance LC resonator is consisted of a parallel-tuned LC resonator in shunt with a series resonant LC tank. The ILFD was implemented with the TSMC 0.18 μm 1P6M CMOS technology and the core power consumption is 3.93 mW at the dc drain-source bias of 0.65 V. At the input power of 0 dBm, the low-frequency band and high-frequency band divide-by-3 locking ranges are respectively from 8.6 GHz to 9.4 GHz (8.79 %) and 16.6 GHz to 17.4 GHz (4.11 %). Finally, we presents a new quadrature cross-coupled voltage-controlled oscillator (QVCO) using a series-tuned resonator. The LC-tank QVCO consists of two bottom-series coupled differential cross-coupled VCOs. At the supply voltage of 0.7 V, the total power consumption is 2.8 mW. The free-running frequency tuning range is 13.35%, tunable from 6.68 GHz to 7.64 GHz as the tuning voltage is varied from 0.0 V to 1.1 V. The QVCO has been implemented with the TSMC 0.18 μm CMOS technology and the die area is 0.854 × 0.854 mm2. The measured phase noise at 1 MHz offset is -118.23 dBc/Hz at the oscillation frequency of 6.81 GHz and the figure of merit (FOM) of the proposed QVCO is about -190.39 dBc/Hz.

Abstract:
Desire for low-power, high performance computing has been at core of the symbiotic union between digital circuits and CMOS scaling. While digital circuit performance improves with device scaling, analog circuits have not gained these benefits. As a result, it has become necessary to leverage increased digital circuit performance to mitigate analog circuit deficiencies in nanometer scale CMOS in order to realize world class analog solutions. In this thesis, both circuit and system enhancement techniques to improve performance of clock generators are discussed. The following techniques were developed: (1) A digital PLL that employs an adaptive and highly efficient way to cancel the effect of supply noise, (2) a supply regulated DPLL that uses low power regulator and improves supply noise rejection, (3) a digital multiplying DLL that obviates the need for high-resolution TDC while achieving sub-picosecond jitter and excellent supply noise immunity, and (4) a high resolution TDC based on a switched ring oscillator, are presented. Measured results obtained from the prototype chips are presented to illustrate the proposed design techniques.<br>Graduation date: 2013<br>Access restricted to the OSU Community at author's request from July 16, 2012 - July 16, 2014

Abstract:
AbstractThe quest for ubiquitous wireless connectivity, drives an increasing demand for compact and efficient means of frequency generation. Conventional synthesizer options, however, generally trade one requirement for the other, achieving either excellent levels of efficiency by leveraging LC-oscillators, or a very compact area by relying on ring-oscillators. This chapter describes a recently introduced class of inductorless frequency synthesizers, based on the periodic realignment of a ring-oscillator, that have the potential to break this tradeoff. After analyzing their jitter-power product, the conditions that ensure optimum performance are derived and a novel digital-to-time converter range-reduction technique is introduced, to enable low-jitter and low-power fractional-N frequency synthesis. A prototype, which implements the proposed design guidelines and techniques, has been fabricated in 65 nm CMOS. It occupies a core area of 0:0275 mm$$^{2}$$ 2 and covers the 1:6-to-3:0 GHz range, achieving an absolute rms jitter (integrated from 30 kHz-to-30 MHz) of 397 fs at 2:5 mW power. With a corresponding jitter-power figure-of-merit of −244 dB in the fractional-N mode, the prototype outperforms prior state-of-the-art inductorless frequency synthesizers.
