Abstract

Det er vist en sensorkrets (10) og en framgangsmåte for å kompensere for område- variasjon i sensorkretsen (10). Sensorkretsen (10) omfatter en transducer (12), et for- skyvningskompenseringsnettverk (32), og et temperatur avfølingsnettverk (38) mono- littisk integrert på et enkelt halvledersubstrat. Transduceren (12) genererer et differensielt signal i respons til en fysisk tilstand, så som tilført trykk. Det differensielle signalet blir kompensert for forskyvning ved forskyvningskompenseringsnettverket (32), Temperaturavfølingskretsen (38) genererer et temperatur avfølingssignal som blir brukt ved en mikroprosessor (34) for å kompensere for variasjon i driftsområdet ved forskyvningskompenseringssignalet. Dermed blir et forskyvning og område temperaturkompensert signal generert i respons til den fysiske tilstanden.
