ABSTRACT:
A calibration system for an asymmetrical ramp generator system for a pulse width modulator wherein a current splitting circuit establishes a slew rate and a calibration level for the first ramp that is the same as the slew rate and the usable voltage range of the second ramp and wherein the first and second sets of ramps are matched so that calibration of the first set results in simultaneous calibration of the second set.
