A design of variable gain amplifier for wireless LAN
무선 LAN을 위한 가변이득 증폭기의 설계
Abstract
A variable gain amplifier(VGA) for wireless LAN is designed using active feedback. The amplifier is controlled by the gate voltage in the feedback path. This amplifier has more than 30㏈ gain variation and a improved linearity in the RF receiver block as input voltage increases. An active feedback topology is used by P-HEMT and is also analyzed for FET equivalent model.
