摘要：A voltage buffer includes a high impedance input and a low impedance output.In one example, the buffer includes a source-follower FET and load FET, at least one ofwhich has a forward-biased source-body junction. Another example includes a cascade of
two source-follower FETs of opposite conductivity types, and corresponding loaddevices. Another example further reduces the buffer's output impedance by using adiode-connected load device. The voltage buffer is effectively referenced to a first powersupply and effectively isolated from a second power supply. Therefore, it tracksvariations in the first power supply voltage, but does not track variations in the secondpower supply voltage.
