This Wilson Current Mirror Tutorial walks through design and implementation of a Wilson Current Source, selection of circuit components including BJT transistors and then the benefits of Wilson design that are highlighted by computing output current, output conductance and output impedance and current source voltage compliance range. For more example see • Electrical Engineering... . This current source circuit is designed with three matched NPN Bipolar Junction Transistors (e.g. MAT14 Analog Devices Matched Quid NPN transistors), one PNP BJT and one Zener Diode. A combination of Kirchhoff circuit laws including KCL and KVL, Early Effect and Early Voltage, and current gain of BJT transistor are used to find output current, output conductance and output impedance and voltage compliance range for this current source circuit.
