A single CCII‐based high‐precision voltage‐mode full‐wave rectifier suitable for low‐level signals

Abstract

SummaryA new second‐generation current conveyor‐based full‐wave rectifier (FWR) is proposed in this work. The proposed voltage‐mode FWR comprises a single active building block, four diodes, and three grounded resistors without needing any passive element matching problems. It does not suffer from any bias voltages and/or currents; therefore, it does not need extra circuitry. It can simultaneously provide positive and negative rectifications; thus, it is flexible. The proposed FWR has high input impedance; accordingly, it can be easily cascadable. Several simulations via the SPICE program and some experiments by using the AD844s are achieved. 0.18‐μm TSMC CMOS technology parameters are used in the simulations.
