Abstract :
A design of a current differencing buffered amplifier (CDBA) using only NPN transistors is proposed in this paper. The proposed CDBA is simple and is designed to operate with a minimum power supply of 2 volts. The PSPICE simulation results demonstrating the circuit performance are included. An example application using the proposed CDBA as active components in the realization of the current-mode universal active filter also included
