Abstract :
A current-domain first-order all-pass filter-section has been developed, composed of a single capacitor and CMOS circuits with linear resistive input impedance, based on the square-law characteristic of an MOS transistor in saturation. Experimental verification has been performed by means of an integrated cascade of 26 identical all-pass sections acting as a continuous-time delay-line.
