Abstract :
A linear BiCMOS transconductance amplifier based on a MOS transistor operated in the linear region is presented. The circuit uses regulated cascode techniques to restrict the variation of the drain-source voltage of the MOS device and hence enhance the linearity of the V-I conversion. Simulation results confirm that the proposed circuits have superior linearity compared with other transconductance amplifiers operating in the linear region
