OverviewThis text deals with the 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. Topologies for high linearity are presented, as well as a novel method for estimating the intermodulation distortion of a wideband signal. An enhanced feedback configuration is presented called feedback boosting that is capable of very low distortion. A statistical method for relating the intermodulation distortion of a wideband signal to the total harmonic distortion (THD) of a single tone is also shown. 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 topologies are presented together with measurement results. The audio amplifiers are built in CMOS and are capable of driving eight 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. This book is a reference for researchers and designers of integrated amplifiers, and may be used as a text for advanced courses on the topic.
