Abstract

A new wide range BiCMOS transconductor and a multiplier were presented. Simulation results show that for a power supply of ±5 V, the linear input range of this transconductor is over ±4 V with the linearity error less than 2%. The total harmonic distortion is less than 0.69% with input range up to ±3 V. Its -3 dB bandwidth is 54 MHz. A new BiCMOS multiplier is also presented. Its linear input range is over ±2.5 V with the linearity error less than 1%. Its -3 dB bandwidth is over 60 MHz. The proposed circuits are expected to be useful in analog signal-processing applications
