A simple difference amplifier circuit is shown in Figure 4.1. Why would replacing the common feedback resistor RE with a constant current source (sink) improve performance? Discuss the operation of a difference amplifier when arbitrary signals are applied at both of its inputs. Define its key figure of merit, the CMRR.
