DESIGN OF CURRENT MODE MULTIPLIER/DIVIDER CIRCUIT USING A CURRENT DIFFERENCING BUFFERED AMPLIFIER

Abstract

A design of multiplier/divider circuit using a single Current Differencing Buffered Amplifier (CDBA) is presented. Here the objective is to simultaneously realize a multiplier and a divider without changing the circuit configuration which achieves less power consumption. It uses the Trans Linear technique to find out the theoretical output of the circuit. Here the current mode approach is used which is suitable for low voltage high speed analog circuit design. The proposed structure is implemented in 180-nm CMOS technology in cadence virtuoso environment. The power consumption is found to be reduced whose value is 45.67µw and the bandwidth of the designed circuit is found to be improved whose value is 83.6 MHz.It achieves more simplicity and flexibility compared to existing designs and is free from parasitic capacitance.
