摘要：
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 simulations of the multiplier in a 0.18 pm standard CMOS technology show an input range of (1 + m) x 10 mu A (where 'm' is an adjustable parameter), a THD of 1% (@ 1 MHz), a - 3 dB bandwidth of 332.3 MHz (for m = 3) and a power consumption of 186 mu W.
