Publisher's Synopsis
An amplifier is an electronic device that increases the voltage, current, or power of a signal. Amplifiers are used in wireless communications and broadcasting, and in audio equipment of all kinds. Electronic circuit design comprises the analysis and synthesis of electronic circuits. The text Electronic Amplifiers and Circuit Design presents the basic principles of amplifiers and circuit design, basic per-stage building blocks, and feedback. A surface acoustic wave (SAW) based micro force sensor is designed in first chapter, which is based on the theories of wavelet transform, SAW detection, and pierce oscillator circuits. Second chapter presents a system-level method to decrease the power consumption of integrated audio Class-G amplifiers for mobile phones by using the same implementation of the level detector, but by changing the parameters of the switching algorithm. Third chapter addresses the engineering of semiconductor optical amplifier (SOA) gates for high-connectivity integrated photonic switching circuits. In fourth chapter, we propose a circuit that reduces the sense amp offset using an auto-zeroing scheme with automatic temperature, voltage, and aging tracking. Evolvable metaheuristics on circuit design have been discussed in fifth chapter. Sixth chapter describes the design of a switched capacitor negative feedback circuit for a very low level dc current amplifier. In seventh chapter, a form of the multi-beamforming signal and a nonlinear model with memory for power amplifier (PA) are given. In eighth chapter, a novel ULCA aiming at the application of signal pre-amplification in the integrated biosensing system has been proposed and verified by using SMIC 0.18 ?m CMOS technology. Ninth chapter presents a track-and-hold amplifier (THA), based on the switched emitter follower topology, suitable for emerging receiver's architectures and data acquisition systems. Tenth chapter focuses on symbolic analysis of analog circuits containing voltage mirrors and current mirrors. In eleventh chapter, the frequency stability of small-signal high-speed amplifier circuits using Bode criterion has been analyzed theoretically. In twelfth chapter, using a new circuit model for EDFAs, the static and dynamic characteristics of EDFAs can be analyzed conveniently through the aid of a SPICE simulator. The switched mode power amplifiers have been presented in last chapter.
