RF (Radio Frequency) power amplifiers form part of the fundamental building blocks of an electronic communication system. RF power amplifiers can also be one of the major causes of distortion in an electronic communication system.

This work focused on evaluating a single-ended complementary push-pull topology for LTE system-on-chip RF pre-power amplifier, to increase power efficiency compared to an existing class-A amplifier. Suitability of the push-pull topology was studied against strict linearity specification. Frequency range in this study was 1710–2020 MHz, and 10 dBm sine wave output power was targeted. Common source and source follower amplifier variants were designed and simulated in a schematic level. Gain control functionality was implemented by dividing the amplifier into controllable partitions. Output DC-vo

Abstract:

The number of mobile wireless devices on the market has increased substantially over the last decade. The frequency spectrum has become crowded due to the number of devices demanding radio traffic and new modulation schemes have been developed to accommodate the number of users. These new modulation schemes have caused very poor efficiencies in power amplifiers for wireless transmission systems due to high peak-to-average power ratios (PAPR). This thesis first presents the issue with classical power amplifiers in modern modulation systems. A brief overview of current attempts to mitigate this

The advancement of the mobile communication industry increases the need for RF power amplifier (RFPA) to be more efficient and linear. The communication network that is shifting towards smaller micro-cell or nano-cell network has also motivated the design of the RF power amplifier to be simple, compact and cost efficient. In this research work, a novel technique for efficiency and linearity improvement of the RFPA is presented. A simplistic approach in the technique called ‘Auxiliary Envelope Tracking' (AET) system has promoted the design for small and straightforward AET tracking generator, a

Over the last decade, the number of mobile wireless devices on the market has increased substantially. New “multi-carrier” modulation schemes, such as OFDM, WCDMA, and WiMAX, have been developed to accommodate the increasing number of wireless subscribers and the demand for faster data rates within the limited commercial frequency spectrum. These complex modulation schemes create signals with high peak-to-average power ratios (PAPR), exhibiting rapid changes in the signal magnitude. To accommodate these high-PAPR signals, RF power amplifiers in mobile devices must operate under backed-off gain

Ever since the FCC allocated 7.5 GHz (from 3.1 GHz to 10.6 GHz) for ultra wideband (UWB) technology, interest has been renewed in both academic and industrial circles to exploit this vast spectrum for short range, high data rate wireless applications. The great potential of UWB lies in the fact that it can co-exist with the already licensed spectrum users and can still pave the way for a wide range of applications. However, this wide bandwidth complicates the circuit level implementation of key RF blocks like the power amplifier (PA), transmit/receive switch, low noise amplifier (LNA) and m

Abstract:

CMOS RF circuit design has been an ever-lasting research field. It gained so much attention since RF circuits have high mobility and wide band efficiency, while CMOS technology has the advantage of low cost and better capability of integration. At the same time, IC circuits never stopped scaling down for the recent many decades. Reliability issues with RF circuits have become more and more severe with device scaling down: reliability effects such as gate oxide break down, hot carrier injection, negative bias temperature instability, have been amplified as the device size shrinks.

However, the output power and linearity is limited by some gain compression mechanisms, such as knee voltage, pinch-off voltage, breakdown voltage and the maximum drain current. These mechanisms compress constant linear gain and then saturate output power as input power increases. The waveform clipping effects cause gain compression in MESFETs. Each gain compression mechanism has its own signature in average RF gate and drain currents.

碩士<br>義守大學<br>電機工程學系碩士班<br>99<br>In this paper, a low noise amplifier (LNA), operated at 1.92GHz-1.98GHz and used in WCDMA system, was designed and analyzed. The active device for the LNA was Heterojunction Biploar transistor (HBT) fabricated on GaAs substrate. First, the nonlinear model of the HBT was established according to the datasheet provided by the fundry. Followed by the design of DC bias, input matching, and output matching. Finally, the LNA was fabricated and the performance was measured through a print circuit evaluation board. The measurement and simulation results were compared a

碩士<br>中華大學<br>電機工程學系碩士班<br>88<br>This thesis is dedicated to the design of the RF power amplifier used in the 2.4GHz ISM band. Compactness is the key concerns in our circuit design. By employing the IC design process, the amplifier size is greatly reduced. In addition, the IC area and the cost of this design could be lowered by minimize the number of matching devices

碩士<br>中華大學<br>電機工程學系碩士班<br>89<br>This paper is talking about basic theory of each RF power amplifiers, and many design technology of circuit. Moreover, we implement a MMIC Class A power amplifier which operating frequency is 2.4GHz ISM band (Industrial、Scientific and Medical band) to prove the related theories. The operating frequency range of our power amplifier is 2.4 ~ 2.483 GHz, and DC power supply is 3V. We use InGaP/GaAS power HBT process of GCS to design our circuit by matching S-parameter and optimum load for

Abstract:

碩士<br>明新科技大學<br>電子工程研究所<br>97<br>In this paper, a radio frequency (RF) CMOS low noise amplifier for WiMAX applications is presented. Typically, the inductance load is applied with a passive spiral inductor. However, inherently low Q-factors and occupied large chip area of the passive inductors, the gain and the cost-performance will be significantly decreased in the amplifier designs. Hence, an active inductor can employ in the load of the amplifier to improve these disadvantages. In order to obtain optimum characteristics, the common-gate configuration and the differential output are employed

Abstract:

碩士<br>國立臺灣大學<br>電機工程學研究所<br>88<br>In last few years, the remarkable growth in the personal wireless communications has motivated great interests in monolithic CMOS transceivers. Therefore, to implement a high efficiency power amplifier in a standard CMOS technology is one of the important challenges in the transceiver integration. In this thesis, the design and implementation of a power amplifier are described. However, the implementation of CMOS power amplifiers suffers from many disadvantages of the intrinsic CMOS characteristics. The handicaps include insufficiency driving capabi
