Low-voltage low-power and high-swing current differencing buffered amplifier

A high performance CMOS current differencing buffered amplifier (CDBA) is presented in this paper. The proposed circuit operates with the power supplies of plusmn0.75 V and consumes low power. HSPICE simulations show that the proposed CDBA provides better performance in nearly all parameters than the previous ones. As an application example, a second-order notch filter is chosen from the literature to demonstrate the performance of the proposed circuit.
