Abstract
- The paper introduces a new circuit structure of precision full-wave rectifier, without the requirement of any diode(s) and passive component(s), which operates in current mode. The proposed structure of the rectifier employs a single current follower differential input transconductance amplifier and two MOS transistors only. The use of the least number of active components makes the circuit structure simple and favorable to the contemporary integration technology. The proposed rectifier has wider input current dynamic range (±1.6 mA), lower current offset (84 pA), and can operate up to 30 MHz frequency. Additionally, the circuit is easily cascadable, temperature insensitive, and less affected by process variation, MOS transistors mismatch, and supply voltage variation. The rectifier circuit is verified through 0.18 µm gpdk technology-based post-layout simulation results using the cadence Virtuoso tool. The rectification accuracy is examined through the parameters, such as average value ratio and root mean square error. The proposed rectifier's layout measures 31.95 µm × 31.35 µm in size.
