【 摘 要 】
References(4)Cited-By(3)This paper presents a new class AB folded-cascode operational amplifier in standard CMOS technology for fast-settling switched-capacitor circuits. The proposed amplifier employs the class AB operation in both nMOS and pMOS output current source transistors by employing only a few passive components without any extra static power dissipation and results in large slew rate, enhanced unity-gain bandwidth and DC gain, and reduced input-referred noise compared to the conventional folded-cascode amplifier. Circuit level analysis and simulation results are provided to verify the effectiveness of the proposed amplifier.
