Abstract
A method for measuring output current of a charge pump, the method including providing a charge pump including a plurality of n charge pump stages, wherein an output of stage n−1(Vo) is output to stage n, an output voltage of stage n being referred to as charge pump voltage output Vout, connecting an additional output pass device to the output of stage n−1, an output voltage of the additional output pass device being referred to as Voutm, forcing Voutm to be at least approximately equal to Vout, drawing at least one of output voltage (Voutm) and output current (Ioutm) from the additional output pass device, measuring Ioutm (e.g., comparing Ioutm with a reference current), and correlating Iout with Ioutm.
