Question Solved1 Answer Suppose that we need an amplifier with input resistance of 500 k22 or greater and a voltage gain of -10. The feedback resistors are to be implemented in integrated form and have values of 10 k 2 or less to conserve chip area. Choose a suitable circuit configuration and specify the resistance values. Finally, estimate the resistor tolerance needed so that the gain magnitude maintained within 5 % of its nominal values.
