[Experiment 12] Source Follower
①
The source follower features a very high input resistance (ideally, infinite), a relatively low output resistance ( ), and an open-circuit voltage gain that is near unity (ideally, unity). Thus the source follower is ideally suited for implementing the unity-gain voltage buffer of Fig. 7.41(c). The source follower is also used as the output (i.e., last) stage in a multistage amplifier, where its function is to equip the overall amplifier with a low output resistance, thus enabling it to supply relatively large load currents without loss of gain (i.e., with little reduction of output signal level). For example, the impedance of the speaker is as small as several ohms, and running directly with a common source amplifier reduces the voltage gain a lot.
