Abstract
In this paper, a new high frequency and high precision half-wave rectifier circuit which is very suitable for CMOS technology implementation is presented. The system comprises a voltage to current converter, a dual output precision current-mode half-wave rectifier, and two current to voltage converters. An input voltage signal is converted into a current signal by using a current conveyor and a MOS resistor. The current signal is rectified using a dual output class-AB precision rectifier cell and then converted into two output voltages by using grounded MOS resistors. This class-AB current-mode precision rectifier is employed for providing high frequency performance. Simulated rectifier results based-on a 0.5 µm CMOS technology with ±1.2 V supply voltage demonstrates very high operating frequency, very precise rectification and good temperature stability.
