Fast voltage-mode full-wave rectifier using CCII and DXCCII

The paper deals with the design and performance analyses of a fast voltage-mode full-wave rectifier. In the structure the second-generation current conveyor and dual-X current conveyor have been used as active elements. The circuit features with maximal simplicity as only two diodes and two resistors are necessary. To enable high-frequency signal processing, current sourcing of the diodes is used with advantage. Using the CMOS implementation of the active elements, the performance of the rectifier was analyzed by evaluating the frequency dependent RMS error and DC transient value for different values of input voltage amplitudes.
