In this dissertation, several crucial aspects concerning power amplifiers' performances on thermal management, linearity and bandwidth are discussed. We proposed and explored a novel ballast resistor network to alleviate the thermal issue exists in power amplifier cells. It shows that the novel network can achieve a more uniform temperature distribution than the conventional one. A power amplifier's linearity is improved by about 3dB using our programmable predistortion linearizer implemented as input stage. Then we discuss that RLC high frequency loss compensation network works as a bandwidth enhancement technique not only at small-signal but also at large signal condition. The RLC network is utilized on a cascode amplifier, saving design efforts for an extra linearizer stage. Explanation is given regarding why RLC can improve bandwidth and linearity. Volterra series method is used to demonstrate the RLC effects on nonlinear condition. Combining those previously discussed techniques, a broadband WiMAX linear power amplifier is designed. Some previous work used different power amplifier in one module to cover different WiMAX band with bias circuit toggling on and off. In contrast to it, the highlight of our design is that one power amplifier with one input/output matching networks shall be able to cover currently existing WiMAX bands from 2.5GHz to 5.8GHz. The power amplifier is composed of two cascode stages. The die size is 1.8mm & times 1.4mm. The gain is 29dB, output power is 30 dBm and PAE is 21% at P1dB. EVM is about 5% at output power level of 25dBm at 3.6GHz. To the best of our knowledge, this is the first time to use RLC network in a power amplifier design to improve bandwidth and linearity. Also, the broadband WiMAX linear power amplifier is a first demonstration to cover all three existing WiMAX bands in one power amplifier design.

Broadband RF and Microwave Amplifiers provides extensive coverage of broadband radio frequency (RF) and microwave power amplifier design, including well-known historical and recent novel schematic configurations, theoretical approaches, circuit simulation results, and practical implementation strategies. The text begins by introducing two-port networks to illustrate the behavior of linear and nonlinear circuits, explaining the basic principles of power amplifier design, and discussing impedance matching and broadband power amplifier design using lumped and distributed parameters. The book then: Shows how dissipative or lossy gain-compensation-matching circuits can offer an important trade-off between power gain, reflection coefficient, and operating frequency bandwidth Describes the design of broadband RF and microwave amplifiers using real frequency techniques (RFTs), supplying numerous examples based on the MATLAB® programming process Examines Class-E power amplifiers, Doherty amplifiers, low-noise amplifiers, microwave gallium arsenide field-effect transistor (GaAs FET)-distributed amplifiers, and complementary metal-oxide semiconductor (CMOS) amplifiers for ultra-wideband (UWB) applications Broadband RF and Microwave Amplifiers combines theoretical analysis with practical design to create a solid foundation for innovative ideas and circuit design techniques.

Highly Linear Integrated Wideband Amplifiers: Design and Analysis Techniques for Frequencies from Audio to RF deals with the complicated issues involved in the design of high-linearity integrated wideband amplifiers for different operating frequencies. The book demonstrates these principles using a number of high-performance designs. New topologies for high linearity are presented, as well as a novel method for estimating the intermodulation distortion of a wideband signal. One of the most exciting results presented is an enhanced feedback configuration called feedback boosting that is capable of very low distortion. Also important is a statistical method for relating the intermodulation distortion of a wideband signal to the total harmonic distortion (THD) of a single tone. The THD, as opposed to the intermodulation distortion of the wideband signal, is easy to measure and use as a design parameter. Three different applications where high linearity is needed are identified, namely audio power amplifiers, wideband IF amplifiers and RF power amplifiers. For these applications high-performance integrated amplifier designs using novel topologies are presented together with measurement results. The audio amplifiers are built in CMOS and are capable of driving 8Omega loudspeaker loads directly without using any external components. One of the designs can operate on a supply voltage down to 1.5V. Both bipolar and CMOS wideband IF amplifiers are built; they are fully differential and have linearity from DC to 20 MHz. Finally, an RF power amplifier is built in CMOS, without using inductors, in order to investigate what performance can be achieved without them. Highly Linear Integrated Wideband Amplifiers: Design and Analysis Techniques for Frequencies from Audio to RF is an excellent reference for researchers and designers of integrated amplifiers, and may be used as a text for advanced courses on the topic.
