Telescopic OP-AMP With Slew Rate Control |
| 摘要 |
An operational amplifier includes a transfer circuit, a cascode control circuit, and a slew rate boost circuit. The transfer circuit is configured to apply a transfer function to a received input signal and the application of the transfer function to the received input signal is effective to create an output signal. The cascode circuit is coupled to the transfer circuit. The cascode circuit is configured to increase an open loop gain of the operational amplifier. The slew rate boost circuit is coupled to the cascode circuit. The slew rate boost circuit is configured to increase the slew rate of the operational amplifier without necessarily increasing the power consumption of the operational amplifier. |

1. An operational amplifier, comprising:
a transfer circuit, the transfer circuit configured to apply a transfer function to a received input signal and the application of the transfer function to the received input signal being effective to create an output signal; a cascode circuit coupled to the transfer circuit, the cascode circuit configured to increase an open loop gain of the operational amplifier; a slew rate boost circuit, the slew rate boost circuit coupled to the cascode circuit, the slew rate boost circuit configured to increase the slew rate of the operational amplifier without necessarily increasing the power consumption of the operational amplifier. |
