Abstract
A system and method is disclosed, to generate an AC signal having a positive and negative half-cycles, each comprising a plurality of PWM pulses each with an individually designated pulse width, the system comprising: a first clock circuit; a second, faster, clock circuit; clock ratio measurement circuitry configured to output a first measurement being a ratio of frequencies; a propagation delay circuit configured to measure a number of propagation elements through which a bit transition propagates within a second clock signal period; pulse data calculation element configured to determine pulse shaping data; and for each of the half-cycles, a respective pulse synthesis circuit configured to synthesise the respective plurality of PWM pulses, each pulse having a respective start defined by the first clock signal, and a pulse width defined by the pulse shaping data and synthesised from the second clock and an output pulse from the propagation delay circuit.
