Abstract
In this paper, a CMOS realization of the current differencing buffer amplifier (CDBA) in the low voltage is presented. The circuit is suited for CMOS implementation. A first order all-pass filter circuit was chosen as an application example in order to demonstrate the performance of the CDBA. The SPICE simulation results for frequency response as well as transient response are incorporated to verify the theory. The feasibility of the proposed first-order all-pass filter is illustrated on the design of a quadrature oscillator.
