Kacar and Mahmut have proposed a single DVCC based configuration to realize first-order current-mode allpass filters only. This paper has exploited this configuration to realize a wider class of current transfer function T(s), which has a pattern of poles and zeros of 1-T(s) as one of the four permissible patterns. Bilinear and biquadratic functions are dealt with in detail. It is shown that only bilinear functions can be realized with all the four passive elements grounded. The First-order all-pass function is a special case that needs only three elements (2R, 1C) or (1R, 2C). A biquadratic function requires (2R, 2C) elements and has all the capacitor grounded. The design of the second-order allpass function is also given.
