WebAs many others pointed out, the voltage across the diode is not constant, and is given by the same equation: Vbe = Vt*ln (Ic/Is). This means the collector current for both transistors is equal. It's only a 1:1 current mirror if the diode exactly matches the BJT (is at the same temperature and has the same Is).

(b) … WebMar 22, 2012 · The basic diode equation is: n = Diode ideality factor (process dependent) k = Boltzmann’s constant T = Temperature (Kelvin) q = Electron charge Ic = Diode current Is = Reverse saturation current (process dependent) Note: An astute reader may notice that a “+ 1” term was neglected in the above equation. WebV BB, the base voltage of a bipolar junction transistor, or in other words, the voltage that falls across the base of the transistor, is crucial to calculations such as when calculating the base current, I B or the quiescent emitter current, I EQ. V BB is calculated by the formula below: Example Related Resources child support guidelines in california
