A Versatile Class-AB Four-Quadrant Analog Multiplier
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.
