Abstract
Five new configurations realizing canonical first-order voltage-mode all-pass filter configurations using a single current differencing buffer amplifier (CDBA) are given. Two of these filter configurations, which were also canonical all-pass filters, contained four passive elements, while the others contained five passive elements. The circuits are suited for CMOS implementation. The SPICE simulation results for frequency response as well as transient response are incorporated to verify the theory.
