Figure 1 shows an operational amplifier circuit with twocurrent sources to model its bias currents. Theoperational amplifier gain element can be consideredideal. Determine an expression for the output of the

amplifierdue to the input voltage and the two bias currentsoperating simultaneously. Determine how you would select the value of Rx toremove the bias current error from the output of theamplifier (R1 = 10kn and R2 = 30 kQ).
