Abstract :
A class AB tunable transconductor is presented, featuring low quiescent power consumption. Class AB operation is achieved using quasi-floating gate transistors. Highly linear tuning is obtained using resistive dividers implemented by transistors operating in triode region. Simulation results for a low-cost 0.5μm standard CMOS process are presented, validating the proposed approach.
