Systems and methods for producing dithered charging signals

A method of generating a shaped charge signal comprising:

• providing a charging circuit comprising a switch modulator in electrical communication with at least a first switching element within a shaping circuit;
• providing an input charge supply to the first the switching element;
• generating, at the switch modulator, a first instruction signal for controlling the first switching element, wherein the first instruction signal comprises a first sample period, wherein the first sample period is divided into a plurality of PWM cycles, each PWM cycle having a PWM duty cycle;
• operably controlling the first switching element via the first instruction signal such that, within the first sample period, a first of the plurality of PWM cycles has a first duty cycle and a second of the plurality of PWM cycles has a second duty cycle different from the first duty cycle.
