Designing a Voltage Follower Circuit Welcome to your Designing a Voltage Follower Circuit You are designing a circuit that requires a precision voltage reference. You decide to use an operational amplifier in the unity gain configuration as a voltage follower to buffer the voltage reference. The voltage reference produces an output of 2.5 volts, and you want to ensure that the output impedance of your voltage follower is as low as possible to minimize loading effects on the voltage reference. Given the operational amplifier's datasheet, which specifies an open-loop gain of 10^6 and an input impedance of 10^6 ohms, calculate the approximate output impedance of the voltage follower circuit.
