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. |
