A Wilson current mirror is a three-terminal circuit (Fig. 1) that accepts an input current at the input terminal and provides a "mirrored" current source or sink output at the output terminal. The mirrored current is a precise copy of the input current.
[nb 2] A small-signal analysis for an op amp with finite gain A v but otherwise ideal is based upon Figure 5 (β, r O and r π refer to Q 2). To arrive at Figure 5, notice that the positive input of the op amp in Figure 3 is at AC ground, so the voltage input to the op amp is simply the AC emitter voltage V e applied to its negative input ...
A signal booster is a system which increases, or appears to increase, the power of a radio signal. The term may refer to: Radio repeater; Relay transmitter;

Figure 2: Small-signal circuit for finding output resistance of the Widlar source shown in Figure 1. A test current I x is applied at the output, and the output resistance is then R O = V x / I x. An important property of a current source is its small signal incremental output impedance, which should ideally be infinite.
