Voltage-mode full-wave rectifier based on DXCCII

The paper deals with the design and performance analyses of a current conveyor based voltage-mode full-wave rectifier. In the structure of the proposed non-linear circuit the second-generation current conveyor and dual-X current conveyor have been used as active elements. In the circuit the current sourcing scheme of the diodes is used to enable high-frequency signal processing. Except the active elements and only two rectifying diodes, other two resistors are required, generally operating as simple voltage-to-current and current-to-voltage converters. 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 magnitudes. Furthermore, using readily available integrated circuits, the performance of the proposed structure has also been verified by experimental measurements that show the feasibility of the voltage-mode full-wave rectifier.
