A new chopper modulator circuit

This paper presents new chopper modulators which can able assign three modulators in one circuit. It consists of Cowan, Ring and amplitude modulators. The proposed circuit is implemented from the different voltage current conveyor, four-MOS transistors switch and two-MOS transistors inverter. The advantage of this proposed circuit is high-input and low-output impedance and is able to connect with any load without buffer and the number of transistor is quite less which is suitable for integrated circuits. The technique is to control the switch by using the square pulse which is obtained from direct signal generator. All simulation results are base on the PSPICE program simulator which confirms the performance of the proposed circuit and technique.
