Hi,could anyone explain to me those two things,please?
1. What is the path of the Input offset current and what is the Vout caused by it. It flows through Rx, thus V+ is IosxRx. The same voltage must be at V. Then what? 2. What is the difference between inverting and noninverting opamp when bandwidth is calculated? For the noninv the gainxbandwidth product is constant but for inv is not. How is the 3dB calculated? An example with those two types would help a lot. Thanks.
