Description: Variable gain amplifier circuit of the analog unit, a change is the gain, adjust the signal dynamic range, stability and the role of signal power. This paper reviews the CMOS integrated variable gain amplifier of the situation given the definition of a variable gain amplifier, application, classification and key indicators, describes a variety of open and closed loop amplifier structure, analysis methods and the corresponding gain control The advantages and disadvantages illustrates the CMOS process to achieve changes in amplifier gain in several ways according to index. Finally, introduced for wireless digital communications, with broadband high linearity and low supply voltage high-performance variable-gain amplifier design examples.
