It consists of a first-order current-mode pseudo-exponential circuit and a current-mode multiplier. Based on the Taylor's series expansion, the pseudo-exponential circuit can be realised by MOSFETs in saturation. The proposed circuit has been fabricated in a 0.5 μm N-well CMOS process with a gain control range of 15dB. The experimental results confirm the feasibility of the proposed variable-gain amplifier.application/pdf221769 bytesapplication/pdf[SDGs]SDG7Amplifiers (electronic); Gain control; Integrated circuit manufacture; MOSFET devices; Current-mode multipliers; Variable gain amplifiers; CMOS integrated circuitsjournal article10.1049/el:200105932-s2.0-0035811822WOS:000169821800002
