Abstract
A new precision full-wave rectifier employing only two differential difference current conveyors, which is very suitable for CMOS technology implementation, is presented. The proposed rectifier is the voltage-mode circuit, which offers high-input and low-output impedance hence it can be directly connected to load without using any buffer circuits. PSPICE is used to verify the circuit performance. Simulated rectifier results based-on a 0.5 µm CMOS technology with ±2.5 V supply voltage demonstrates high precision rectification and excellent temperature stability. In addition, the application of proposed rectifier to pseudo RMS-to-DC conversion is also introduced.

Summary
Full-wave rectifier is used in RF demodulator, piecewise linear function generator, AC voltmeter, watt meter and various nonlinear analog signal processing circuits. The precision rectifiers based on operational amplifier (op-amp), diodes and resistors are presented [1,2,3,4]. The gain-bandwidth is a parameter of op-amp that limits the high frequency performance of this scheme Since these structures use the op-amp and the resistors; these circuits are not suitable for IC fabrication. Second-generation current conveyors (CCIIs) is possessed a very high slew rate and bandwidth if compared to the traditional op-amp. This makes the CCII of primary importance in the design of modern analog integrated circuits.
