Analog Signal Conditioning in Instrumentation
Robert B. Northrop · 2018
This chapter deals with the analysis and design of analog signal-conditioning circuits. The designer of an analog signal-conditioning system for an instrumentation system faces a bewildering array of op-amp (OA) types and specifications. Current feedback op-amps constitute a relatively new class of OA that offers certain design advantages in terms of independent control of gain and bandwidth, and they generally have very high slew rates. The chapter also deals with the ubiquitous operational amplifier amp that finds many applications in linear and nonlinear signal processing. It explores basic quadratic analog AF designs using conventional OAs. The chapter also explores the nonlinear analog signal processing. It discusses the systems properties of integrated circuit operational amplifiers of various types. The chapter examines the use of OAs to make single-ended, broadband amplifiers. The system&s;s nonlinear signal processing requirements demand a broadband logarithmic nonlinearity, which can operate on video-frequency signals.
