文摘

An analog baseband chain for a synthetic aperture radar receiver implemented in a 130?nm CMOS technology is presented in this paper. Occupying 0.23?mm2 of silicon area, the baseband chain consists of a three-stage variable gain amplifier (VGA), a 5th-order gm-C low-pass filter (LPF) and an output buffer. The gain of the chain can be controlled by tuning the control voltages of the VGA and has a range from 25 to 34?dB. 8?dB of the gain is embedded into the LPF. The bandwidth of the LPF is programmable from 100 to 190?MHz by means of capacitor matrices. The chain, which uses a 1.2?V supply voltage, achieves an input-referred noise density of 4?nV/ $ \sqrt {\text{Hz}} $ and an in-band IIP3 of ?6?dBV rms.
