How to Calculate Output current of the Widlar Current Source?
Output current of the Widlar Current Source calculator uses output_current = (Threshold voltage/Emitter Resistance)*log10(Reference current/Current Value) to calculate the output current, The Output current of the Widlar Current Source formula is defined as a circuit designed to copy a current through one active device by controlling the current in another active device of a circuit, keeping the output current constant regardless of loading. output current and is denoted by i symbol.
How to calculate Output current of the Widlar Current Source using this online calculator? To use this online calculator for Output current of the Widlar Current Source, enter Threshold voltage (V_{T}), Emitter Resistance (r_{e}), Reference current (I_{ref}) and Current Value (CV) and hit the calculate button. Here is how the Output current of the Widlar Current Source calculation can be explained with given input values -> -0.522879 = (50/50)*log10(30/100).
