A low voltage and low power current-mode field programmable analog computational unit
A new current-mode analog computational unit (ACU) is presented. The ACU can be digitally programmed to produce multiplying, squaring and inverse functions. The design is based on using MOSFETs operating in subthreshold region to achieve ultra-low power dissipation. The circuit is operated from a ± 0.75V DC supply. The proposed circuit has been simulated using Tanner in 0.35μm TSMC CMOS process. Simulation results confirm the functionality of the circuit. The total power consumption is 2.3μW, total harmonic distortion is 1.1%, maximum nonlinearity error is 0.3% and the bandwidth is 2.3MHz.
