Four voltage sources of 3 V, 4V, 2V and 3V respectively are to be applied to the input terminal/terminals of “an" inverting amplifier. Design two different circuits for the two different cases with justified explanation and selection of proper resistances as per the requirements below: a) When an output of 4V is required (with phase shift). b) When an output of 8V is required (without phase shift) Note: Only inverting amplifier/amplifiers to be used for each case and all the voltage sources are to be used for each individual design as required in a) and b). 2.
