2-BIT Pass-Transistor Logic Potentiometric DAC using 0.15um CMOS Technology

Nowadays we need a high-frequency digital circuit that can operate with high accuracy, high speed, and low power for required applications. A 2-bit DIGITAL TO ANALOG CONVERTER(DAC) using PASS-TRANSISTOR logic is presented in this paper to analyze accuracy, linearity, and speed. For accurate DAC operation, integral nonlinearity must be less. This paper introduces a 2-bit DAC format using 150 nm CMOS technology using PASSS TRANSISTOR logic as a switch. TANNER EDA tool is used to simulate the proposed design.
