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

Abstract

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.

Electronically Tunable Full Wave Precision Rectifier Using DVCCTAs

“…Due to the presence of significant interconnection resistance, the distributed resistance and parasitic capacitance will influence the overall performance of the rectifier design and even lead to delays between pre-and post-layout results. The important performance parameter of the rectifier circuit is the DC Value transfer (P DC ) and RMS error (P RMS ) [27,28], which are used to show the accuracy of the rectifier. In the ideal case, the Values of P DC and P RMS should be 1 and 0, respectively.…”

“…A current-mode full-wave rectifier circuit using DDCC along with three passive resistors is presented in [26]. The full-wave precision rectifiers presented in [27,28] do not provide high input impedance and low output impedance. Moreover, it is worth mentioning that the rectifier circuit in [25][26][27][28] does not provide tunability features.…”

Voltage-mode full-wave rectifier based on DXCCII

“…Only two diodes and two grounded resistors are required as passive elements. The main idea of the proposed circuit has been presented by the authors in [22], where using the CMOS implementation of the DXCCII and CCII, the performance of the rectifier was analyzed by evaluating the frequency dependent RMS error and DC transfer value for different values of input voltage magnitudes. Also, SPICE simulations were included showing the feasibilities of the proposed rectifier.…”
