CMOS Programmable Full-Wave Rectifier Using Current Conveyor Analogue Switches

This paper presents a new simply full-wave rectifier in voltage and current mode employing two second generation current conveyors (CCIIs) that can be programmed. The different of bias currents has been used for the CCIIs operating. They are biased currents that are used to controlled by on-off, the so call “current conveyor analog switches (CCASs)”. So, the different of bias currents is used to control the output by programme that the input alternative voltage and current signal is supplied. They will be rectified into two symmetrical voltage and current outputs. The proposed full-wave rectifier can be simultaneously realized to full-wave in voltage and current modes. The proposed full-wave rectifier circuit has been simulated using 0.18 μm CMOS from TSMC. The simulation results are used to confirm the workability of the proposed circuit.
