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 0.35 μm CMOS technology parameters is employed to verify the circuit.
