The basic conflict between speed and precision in amplifier design has led to the development of techniques that are both fast and precise; this high-performance amplification is applied as analog preprocessing for analog-to-digital converters (ADCs), as postprocessing for digital-to-analog converters (DACs), and for amplifiers in test instruments. This chapter examines novel subsystem-level amplifier topologies involving multiple signal paths first and then single-stage amplifiers. These topologies are applied to buffer amplifier design, continued from the previous chapter. Finally, the versatility of controlling or programming amplifier gain leads to a discussion of multipliers and programmable gain amplifiers.
