%X Maheshwari has proposed three differential-voltage current-conveyor configurations for realizing<em> first order all-pass filters</em> only. This paper has exploited these configurations for realizing <em>more complex transfer function T</em>(<em>s</em>)&nbsp;which yield poles and zeros of 1 <span style=\"color:#333333;\">-&nbsp;</span><em>T</em>(<em>s</em>) in one of the four admissible patterns. Bilinear and biquadratic functions are dealt in detail. It is shown that only bilinear functions can be realized with all the four passive elements grounded. First order all-pass function is a special case which needs only three elements (2<em>R</em>, 1<em>C</em>) or (1<em>R</em>, 2<em>C</em>). A biquadratic function requires (2<em>R</em>, 2<em>C</em>) elements and has all the capacitor grounded. Design of second order all-pass function is given.
