Abstract

This paper presents a wideband variable gain amplifier (VGA) applied to 60GHz millimeter-wave receiver with an operating frequency from DC to 1.08GHz and variable gain range from 0dB to 60dB. The entire VGA consists of an 8dB fixed gain stage, a 0~48dB coarse gain control stage, a 0~12dB fine gain control stage and an output buffer stage. Both the coarse gain control stage and the fine gain control stage adopt open loop amplifier with local feedback. The feedback capacitors are added to compensate the bandwidth of the circuit. The VGA circuit is designed in TSMC 65nm CMOS process. The post simulation results show that: the operating current of the entire VGAwith testing buffer is 20mA. The 3dB bandwidth is larger than 1.4GHz. The OP1dB at 0dB gain is 0 dBm. The whole chip area is 1.5×0.6mm2.
