Abstract

Oppfinnelsen gjelder en pulsbredde-modulatorkrets for å generere et referansesignal med et ønsket puls/pause-forhold og som omfatter en justeringsenhet som inkluderer minst ett lagringsregister og en teller, hvor dette lagringsregister er konfigurert for lagring av verdier som tilsvarer det ønskede puls/pause-forhold i det minste tilnærmet, og som blir innstilt under en arbeidsperiode i pulsbreddemodulatorkretsen for å generere et referansesignal, mens telleren innstiller et periodisk tellesignal (Y) som angir hvor ofte en lagret første verdi (X) blir avlest under arbeidsperioden (A) fra lagringsregistret, hvor den verdi som lagres i lagringsregisteret varierer under arbeidsperioden.
