In this paper, a 3-bit flash analog-to-digital converter (ADC) using pass transistors is presented. Using DSCH and MICROWIND software tools, a circuit schematic with three comparators, pass transistor switches, and a 3-bit digital-to-analog converter (DAC) is designed. The gates of the pass transistors, which are managed by the comparator outputs, are coupled to the DAC's output. The circuit layout is then created using MICROWIND, and its functionality is checked using a simulation. The circuit's final mask layout is then produced. With the ability to convert analog signals into digital signals with high accuracy, the developed 3-bit flash ADC employing pass transistors is suited for a wide range of applications, including data collection systems, instrumentation, and communication systems. The simulation results demonstrate that the developed ADC performs well in terms of conversion speed and accuracy. The proposed design could, all things considered, be a viable answer for high-speed and high-accuracy ADC applications.
