Full-Phase Operation Transresistance-Mode Precision Full-Wave Rectifier Designs Using Single Operational Transresistance Amplifier

Abstract

This study proposed the designs of two full-phase operation transresistance-mode (TRM) precision full-wave rectifiers. The first circuit consisted of a single operational transresistance amplifier (OTRA), four diodes, and a resistor. The second scheme was an OTRA combined with a full metal-oxide semiconductor field-effect transistor-based design, which is preferable for integrated circuit implementation because no passive components are used in the circuit topology. Based on our literature review, this is the first study that discussed a full-phase operation transresistance-mode precision full-wave rectifier consisting of a single OTRA and few passive components. In this paper, several previously reported precision full-wave rectifiers consisting of various active devices are first reviewed followed by the proposed OTRA-based transresistance-mode precision full-wave rectifiers and an analysis of nonideal effects. Furthermore, computer simulations and experimental results are presented to verify the validity of the proposed circuits, which were consistent with the theoretical predictions.

Low-Power MISO Biquadratic Filter and Diode-Less Full Wave Rectifier Using CM-BD-MO-OTA for Bio-signals

“…Figures 15 and 16 show the DC transfer characteristics of non-inverting and inverting FWR circuits which depict the maximum processing amplitude limit of these rectifiers, and it is limited to 30 mV [39].…”

“…In the bio-signal processing chain, the low-noise analog instrumentation amplifiers to amplify and full wave rectifier for wave shaping are required [22][23][24]. The half wave and full wave rectifiers are required in analog signal-processing applications such as instrumentations, measurement, control systems [25], sensor interfaces and power converters [26]. Biomedical signal processing is also an emerging field where low-voltage low-power full wave rectifiers are used [27].…”

Current and transconductance mode full/half‐wave rectifiers realized with only one active block

“…However, upon reviewing the literature of previous solutions published within the last decade, it becomes apparent that the proposed solutions possess certain weaknesses. These weaknesses include notable voltage consumption, 7,15,25,27 reliance on diodes, 3,8,10,14,[16][17][18]30 utilization of multiple passive elements, [6][7][8][9]14,30 dependency on an external switch, 5,20,22,26,27 and the lack of output adjustability. [3][4][5][6][8][9][10][11][14][15][16][17][18]22,23,[26][27][28][29][30][31] The paper introduces two distinct rectifier modes of operation, namely, current mode (utilizing MO-CFTA) and transconductance mode (based on MO-VDTA).…”
