Abstract :
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.
