Abstract
A wideband variable gain driver amplifier with shunt resistive-feedback and cascade topology is proposed for software-defined radio (SDR) application. The proposed wideband driver amplifier is implemented in 90 nm CMOS technology. Measurement results show that the power gain is greater than 10 dB and output matching (S22) is better than -10 dB from 0.4 to 6 GHz. The tunable gain ranges from -3 to 18 dB. The OIP3 and power consumption are 4dBm and 10mW, respectively.
