Abstract

In this paper a voltage mode four quadrant analog multiplier (FQAM) using voltage differencing buffered amplifier (VDBA) based on quarter square algebraic identity is presented. In the proposed FQAM the passive resistor can be implemented using MOSFETs operating in saturationregion thereby making it suitable for integration. The effect of non idealities of VDBA has also been analyzed in this paper. Theoretical propositions are verified through SPICE simulations at 0.18μm CMOS technology node and the simulation results are found in close agreement with theoretical values. The supply voltage is taken as ± 1V and the value of the bias current is set to 40µA.The simulated total harmonic distortion (THD) is observed to be under 3% and the total power dissipation is found as 627µW. The workability of the proposed FQAM is also tested through two applications, namely, an amplitude modulator and a rectifier. The simulated results corroborate the theoretical propositions.
