Design of a Wideband dB-Linear Variable Gain Amplifier With Continuous Gain Adjusting in 90-nm CMOS Technology

This paper presents a wideband dB-linear variable-gain amplifier (VGA) with a DC-offset cancellation network in a 90-nm CMOS technology for high-speed applications. The VGA consists of a four-stage Cherry-Hooper amplifier, which is based on a feedback resistor and negative Miller capacitance to obta...
