An op-amp is to be selected for an inverting amplifier to be used at dc and very low frequencies. A closed-loop nominal gain 0f -100 is desired. Specifications indicate the minimum value of dc open-loop gain cannot exceed 0.1dB. Assume in the design of problem with the following additional specifications given:
dc output due to input offset voltage 
100mV
dc output due to input offset voltage
5mV
Determine the maximum value of input offset voltage allowed for
the op-amp. If Ri is selected to meet 10
requirements on input impedance, determine the maximum value of
input offset current allowed for the op-amp, assuming that a
compensating resistance will be used
