Title: Improvements in a basic opamp circuit Post by Analog_Rex on Dec 13th, 2008, 12:45am Hi... I have a basic circuit with an opamp using a simple negative feedback configuration with two resistors. When i tested the circuit, I noticed that for a 1V input it saturates on the positive output. I would want to improve this basic opamp circuit in a way that it does not saturate even when the input is 1mV. Can somebody help me with this? Thank you Rex |

It would be very helpful if you could give us the gain of your opamp stage. |

Thank you. |
