Current Mirror Bjt. This same thing is created for the 2n6660 mosfets. 1 0 basic current mirror fig.
Basic bjt current mirror if a voltage is applied to the bjt base emitter junction as an input quantity and the collector current is taken as an output quantity the transistor will act as an exponential voltage to current converter. Bipolar junction transistor or bjt current mirror an often used circuit applying the bipolar junction transistor is the so called current mirror which serves as a simple current regulator supplying nearly constant current to a load over a wide range of load resistances. 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.
The negative supply rail. First and foremost is the issue of base drive. Basic bjt current mirror if a voltage is applied to the bjt base emitter junction as an input quantity and the collector current is taken as an output quantity the transistor will act as an exponential voltage to current converter. 1 simple bjt npn current mirror and its test circuit in the basic current mirror circuit for a matched pair for transistors i.
