Novel CMOS wide-bandwidth 1st- and 2nd-order current-mode allpass filters are proposed in this paper. The 1st-order filter consists of only one transistor, two resistors and one grounded inductor. An addition of one capacitor converts the 1st-order filter into a 2nd-order filter. A 1st-order allpass filter with delay of approximately 33 ps and pole-zero location of 10 GHz is designed to confirm the circuit operation. The location of the pole-zero pair is confirmed with a current-mode quadrature… CONTINUE READING
