  ABSTRACT: A new precision peak detector/full-wave rectifier of input sinusoidal signals, based on usage of dual-output current conveyors, is presented in this paper. The circuit gives a DC output voltage that is the peak input voltage over a wide frequency range, with a very low ripple voltage and low harmonic distortion. The proposed circuits use an all-pass filter as a 90° phase shifter of the processed input signal. To verify the theoretical analysis, the circuit SPICE simulations results have also been included, showing good agreement with the theory. Inherently, the circuit is well suited for IC implementation.
