High performance low voltage low power voltage mode analog multiplier circuit

Abstract

This paper presents a low voltage low power analogue voltage mode four quadrant multiplier circuit using only two second generation current conveyor circuits (CCII) and two NMOS transistors operating in ohmic region. This circuit is characterized by ± 0.25 V dynamic ranges with a low total harmonic distortion (THD) around to 0.021 %, wide bandwidth (2.67 GHz) and low power consumption of about 0.43 mW. Tspice simulations using 0.18 µm CMOS TSMC parameters are performed to confirm the workability of CCII circuit and voltage mode multiplier structure.
