英文摘要：

A versatile class-AB analog multiplier was presented in this paper.The current squarer/current follower,based on class-AB current mirror and MOS trans-linear（TL） principle,is the basic building block in realization scheme.Since the multiplier can be driven by current,voltage or both voltage and current without changing the internal circuit structure and element parameters,so it is a versatile analog multiplier.The major advantages of this multiplier are wide band-width,low power consumption,and good linearity.As a result,it can be considered as a useful building block in current-mode and voltage-mode circuits.PSPICE simulator with TSMC 0.35μm CMOS technology parameters is employed to verify the circuit.
