A CMOS Analog Cell and its applications in analog signal processing

This paper presents a core cell that can be reconfigured and combined with current mirrors to implement exponential, logarithmic, multiplier, divider and raise-to-power function circuits. The proposed circuit uses CMOS transistors operating in the strong inversion. The proposed circuits has been verified with the 0.8 mu m CMOS technology by HSPICE simulations. The simulations results confirm the functionality of the proposed circuits. The proposed circuits paves the way for designing analog signal processors.
