Abstract

This paper presents a new realization of a low-voltage, high-performance CMOS current-differencing buffered amplifier (CDBA). The proposed circuit can be operated with the power supplies down to plusmn0.75 V and it also consumes less power than its counterparts that have been reported so far. Moreover this CDBA has good voltage and current accuracies. UMC 0.18 mum CMOS technology is used for the simulations. The performance of the CDBA is verified with the HSPICE. To show the performance of the circuit, a second-order current-mode notch filter is selected from the literature. The results are in good agreement with the theoretical ones.
