Design of Wide Dynamic Variable Gain Ampliifer
摘要
Abstract
In order to obtain the stable signal, it demands the gain of receiver automatically change when the received signal changes within a wide dynamic range in the communication receiver. It means that high performance receiver should put forward stricter requirements to variable gain ampliifer. The paper researches and designs the structure for wide dynamic variable gain ampliifer. Based on BiCMOS, this essay aims at the research and design of the wide dynamic variable gain ampliifer with the differential input common emitter structure. The MOS switch which changes the resistance of collector and emitter together with delay control technology contributes to the wide dynamic gain. The chip is simulated by using Cadence’s Spectre software and implementted by using CSMC 0.5μm process. Simulation results indicate that dynamic range of gain is from 0 to 60 dB;it receives the frequency from 20 MHz to 90 MHz, and has the power dissipation less than 20 mW.关键词
