A voltage-mode circuit structure using FinFet Transconductance Topolog

Abstract— FinFet is evolved to overcome Moore's law limitations in nanometer regime. Transconductance circuit produces differential output currents, when differential input voltages are applied. A simple FinFet transconductance circuit structure modified from traditional MOSFET is proposed to preserve both area and power. The proposed design contributes a transconductance gain of 5.247 mA/v for 10 mv peak-to-peak input voltage. Voltage-mode circuit structure of low-power high frequency filters using FinFet transconductance and transimpedance blocks are investigated in this paper. The simulated third-order harmonic distortion with applying a 300 mv (peak-to-peak) differential inputs, remains below -63 dB at 300 MHz frequency.
