Abstract

In this paper, a CMOS realization of the current differencing transconductance amplifier in the low voltage is presented. Proposed circuit can operate in supply rails down to +/- 0.75V. In the input stage, flipped voltage followers are used to obtain very low input resistances and a few tens of ohms of input resistances are achieved. Then, proposed circuit is employed in a novel allpass configuration. To verify the correctness of the realization, SPICE simulation results are also supplied.
