Pulse-width modulation
This application relates to a PWM modulator 400 operable to generate a digital PWM signal wherein signal transitions in the PWM signal are synchronised to a first clock signal CLK 1. It is disclosed that the pulse generator may generate pulses that are not centred within a PWM cycle period. Therefor...

Summary: | This application relates to a PWM modulator 400 operable to generate a digital PWM signal wherein signal transitions in the PWM signal are synchronised to a first clock signal CLK 1. It is disclosed that the pulse generator may generate pulses that are not centred within a PWM cycle period. Therefore, the PWM modulator comprises a pulse position controller 403 configured to monitor any positional error arising from pulses that are not centred within the PWM cycle period and to control the position of a pulse in a subsequent PWM cycle period to compensate for this error. |
