Novel CMOS CFDITA and its application as electronically-tunable bistable multivibrator

This paper presents the CMOS implementation of current follower differential input transconductance amplifier (CFDITA). As an application of presented CMOS CFDITA, a simple circuit of bistable multivibrator consisting of only one multiple-output current follower differential input transconductance amplifier (MO-CFDITA) is also proposed. No passive component is required in the realization of proposed bistable multivibrator. It provides both clockwise and anticlockwise hysteresis simultaneously. Its threshold levels and output amplitude are controllable electronically and independently with the help of input bias currents. The HSPICE simulation results have been depicted to examine the performance of presented bistable multivibrator. It consumes only 1.25 mW power when operated at ±1.25 V.
