New full-wave/half-wave rectifier with electronic control

Abstract This research article introduces an innovative full-wave rectifier design centered around the Voltage Differencing Trans-conductance Amplifier (VDTA) as its foundational core, thereby eradicating the necessity for passive components. The proposed circuit demonstrates high linearity and good zero-crossing performances. The rectified output signal can be adjusted by controlling the bias currents. Its simple and compact design makes it well-suited for integration into IC circuits, especially for low-voltage, high-frequency applications. A detailed analysis of the proposed rectifier includes evaluating non-ideal effects and parasitic influences. By eliminating passive components, the circuit minimizes parasitic effects. Its robustness is evaluated through detailed simulations using 0.18 μm CMOS technology and a ±0.8 V power supply, showing strong agreement with theoretical predictions. Additional reliability insights are obtained via Monte Carlo simulations and corner analysis. To verify the rectifier’s feasibility, practical experiments with off-the-shelf components confirm its functionality and efficiency. The circuit layout is implemented in Cadence Virtuoso, occupying a chip area of 2726 μm 2 .
