Electronically Tunable Full Wave Precision Rectifier Using DVCCTAs

This work presents a voltage mode scheme of full-wave precision rectifier circuit using an analog building block differential current conveyor transconductance amplifier (DVCCTA) including five NMOS transistors. The proposed design is essentially suited for low and high-frequency input signals. operation the depends upon region output waveform presented can be made electronically tunable by controlling bias voltage. functional correctness verification are performed 0.25-µm TSMC technology under supply ±1.5 V. absence resistor leads to minimal parasitic effect. To obtain further insight on robustness circuit, Monte Carlo simulation corner analysis also presented. verified experimentally incorporating breadboard model with help commercially available ICs CA3080 (operational amplifier) AD844AN (current feedback operational offers remarkable compliance both theoretical outcomes. has been laid out Cadence virtuoso, which consumes chip area 9044 µm2.
