N2 - Operational trans-conductance amplifiers (OTAs) are an essential building block in analogue and mixed-signal circuits. In this study, a new two-stage class-AB OTA is proposed. The class-AB operation is obtained without extra power dissipation, and without unity-gain bandwidth or noise degradation. The circuit was fabricated using 1P6M 180-nm CMOS technology under 1.8â€.V supply voltage. The measurement results indicate 13â€.dB enhancement in DC-gain and 1.8 times improvement in slew rate compared to its conventional counterpart. Comparison results indicate that the proposed OTA demonstrates better performance than the state-of-The-Art designs.
