In this paper, the modern nonlinear theory is applied to a third order phase locked loop (PLL) with a feedback time delay. Due to this delay, different behaviors that are not accounted for in a conventional PLL model are identified, namely, oscillatory instability, periodic doubling and chaos. Firstly, a Pade approximation is used to model the time delay where it is utilized in deriving the state space representation of the PLL under investigation. The PLL under consideration is simulated with and without time delay. It is shown that for certain loop gain (control parameter) and time delay val

Abstract:
This paper presents an all digital delay-locked loop (DLL) to achieve wide range operation, fast lock and process immunity. To keep track of any potential phase problem caused by environmental variations, a delay compensation mechanism is employed. Utilizing the delay compensation controller (DCC), the proposed DLL can overcome the false-lock problem in conventional designs. It is fast locking because the DLL’s initial state can be detected by the delay compensation controller and the initial large phase difference can be eliminated. The proposed DLL is implemented in a 0.13μm CMOS process. Th

A Delay-Locked Loop (DLL) for the generation of multiple clock phases/delays is proposed. Several new techniques are used to help enhance the DLLs performance, specifically, to achieve wide lock range, short locking time, and reduced jitter. The DLL can be used for a variety of applications which require precise time intervals or phase shifts. The phase detector (PD), charge pump (CP), and voltage-controlled delay line (VCDL) are the three most important blocks in a DLL. In our research, we have proposed a novel structure which integrates the functionality of both the PD and CP. By using

The correct filtering operation and large-signal transfer characteristic of the PLL are verified with an all-digital DFT solution.

Abstract:
Phased array radar systems employ multiple antennas to create a radar beam that can be steered electronically. By manipulating the relative phase values of feeding signals among different antennas, the effective radiation pattern of the array can be synthesized to enhance the main lobe in a desired direction while suppressing the undesired side lobes in other directions. Hence the radar scanning angles can be electronically controlled without employing the bulky mechanical gimbal structure, which can significantly reduce radar system size, weight and power consumption.

Abstract:
AbstractThe fractional-N frequency synthesis based on Digital Phase Locked Loop (DPLLs) has become a conventional design approach for the new radio wireless applications. The advantage of the digitally-intensive design style is the possibility to implement low-power and very accurate digital calibration techniques. Most of these algorithms run in the background tracking PVT variations and either relax or, in some cases, completely remove the performance limitations due to analog impairments. Moreover, the digital loop filter area is practically negligible with respect to the one in analog PLLs. These benefits become even more relevant in the scaled CMOS technology nodes. This chapter identifies the design parameters of a standard DPLL architecture and proposes a novel locking scheme to overcome the intrinsic limitations of the digital frequency synthesizers approach. To prove this new scheme a sub-6 GHz fractional-N synthesizer has been implemented in 65 nm CMOS. The synthesizer has an output frequency from 3.59 GHz to 4.05 GHz. The integrated output jitter is 182fs and the power consumption of 5.28 mW from 1.2 V power supply leads to a FoM of −247.5 dB. This topology exploits a novel locking technique that guarantee a locking time of 5.6 s, for a frequency step of 364 MHz, despite the use of a single bit phase detector.
