WebFeb 18, 2024 · I made a LTspice simulation of a pmos current mirror. The current source should model a photodiode (without parasitic capacity). The W/L ratio is the same for both Mosfets. I expected the plot of the output current (red) to be the same as the input current (blue). I thought it will rise in a linear manner as the input current (the sweep is linear). WebMOSFET CURRENT MIRRORS OUT What is a Current Mirror? A current mirror replicates the input current of a current sink or current source as an output current. …
