(a) Design an inverting amplifier with a closed-loop gain of-100 and an input resistance of 1 kΩ.
(b) If the op-amp is known to have an open-loop gain of 2000, whatdo you expect the actual closed-loop gain of your design tobe?
(c) Give the value of a resistor you can place in parallel with R1(the resistor between negative input and the input signal source)to restore the closed-loop gain to its nominal value of 100.
