Abstract
This paper presents two improved precision rectifiers, each employing two active elements and two MOS transistors. The new circuits are advantageous when compared to the most recent work [5] by enjoying high input impedance and resistor-less realization, which makes them ideal for CMOS implementation. High precision and wide frequency operation of the circuits is shown along with parasitic insensitivity. The dual-X current conveyor based novel circuits have useful analog signal processing applications and are verified through extensive computer simulations.
