We can likewise define a small-signal emitter resistance: be e e v r iPractical Model for Current Mirror Circuit. The current mirror circuit is simulated using Proteus models. In the left side, the current mirror circuit using 2N2222 BJT is shown where two identical transistor pair is used. Instead of the programming resistor, a potentiometer is used to control the current flow in the live simulation.Hybrid-π model. * Therefore use this model to construct small-signal circuit when v i is operating at high frequency. * Note since 1 C Z = jωC, all currents and voltages will be dependent on operating frequency ω. * Note the voltage across rπ is vπ, but be vπ ≠v !!! * Note at low-frequencies, the model reverts to the original Hybrid-π ...

If no values are specified, the default values are assumed (ß=100; IS=1E-16A, and VAF=[infinite]). Other parameters can be specified ...The conduction level in a bipolar junction transistor (BJT) depends on two charge carriers – electrons and holes. The JFET, however, is a unipolar device because its conduction depends uniquely on one type of carrier – electrons (n-channel) or holes (p-channel). Other essential characteristics of the JFET are: Ease of manufacture.A plastic model is all you have to identify a range of different cars. It's not as easy as you may think!
