• abstract: This paper designed an automatic gain control(AGC) amplifier for CMOS Image Sensor. The AGC amplifier adopts translinear variable gain amplifier (VGA) to realize a good linearity. It detects valley to present the strength of signal, and uses a succinct adjustment circuit to control the gain of VGA. A bandgap reference not needing start-up circuit was designed for the whole system. Simulated in SMIC 0.35um CMOS, it can compressed the dynamic range of 100kHz signal from 55.32dB to 7.36dB.
