Abstract
A novel full-wave precision rectifier circuit employing a single EXCCII, a MOS switch and one resistor is proposed. The proposed voltage-mode full-wave precision rectifier is simple and operates with a supply voltage of ±1.25 V. The circuit provides rectification for a wide range signal amplitudes of −150 mV to 150 mV. The proposed circuit is easily adapted as an extended application in ASK and BPSK generation. Non-idealities of building blocks and parasitic effects are analyzed, Simulations using 0.25 µm parameters are given and comparisons drawn with most recent works, to support the new proposed circuit.
