    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.

    High frequency and high precision CMOS full-wave rectifier
    (2010-12-01)
    Kumngern, Montree
    This paper presents a new high frequency and high precision full-wave rectifier, which is very suitable for CMOS technology implementation. The system comprises a voltage to current converter, precision full-wave rectifiers and a current to voltage converter. An input voltage signal is converted into two symmetrical current signals by using a dual-output operational transconductance amplifier. Two current signals will be rectified by using junction diodes and convert into output voltage by using a grounded MOS resistor. Simulated rectifier results based on a 0.5μm CMOS technology demonstrates very high operating frequency and very precise rectification. © 2010 IEEE.
