In this paper, a novel current mode enhanced input range four-quadrant analog multiplier is presented. The proposed class AB based translinear current squarer allows the designer to control the input range via a digital code. Moreover, the proposed scheme improves the linearity of the circuit and has a high robustness against process variations. The Post-layout and Monte Carlo simulation of the multiplier in a 0.18µm standard CMOS technology shows an input range of (1+m)×10µA (where 'm' is an adjustable parameter), a THD of 1% (@1MHz), a -3dB bandwidth of 332.3MHz (for m=3) and a power consumption of 186 µW.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
