Abstract
This paper introduces a slew-rate enhancement (SRE) circuit for CLASS AB Operational Transconductance Amplifier (OTA). The enhancement is achieved by two auxiliary amplifiers. Simulation results show that CLASS AB OTA with the proposed SRE circuit is achieved 60. 25MV/s positive and 30. 6MV/s symmetric slew rate with a load capacitance of2pF. The positive and negative slew rate of the CLASS AB OTA with the proposed SRE circuit have increased by a factor of 7.03 and 3.23 respectively. The SRE circuit only work during fast signal transitions with the power consumption increased by 8.06%.
介绍了一种用于AB类运算跨导放大器(OTA)的回转速率增强电路。增强是通过两个辅助放大器实现的。仿真结果表明，采用所提出的SRE电路可以实现CLASS AB OTA。25MV/s正极和30。6MV/s对称摆率，负载电容为2pf。采用SRE电路的AB类OTA的正、负摆率分别提高了7.03倍和3.23倍。SRE电路仅在快速信号转换时工作，功耗增加了8.06%。
