Abstract
Forsterkerkrets (1) for å forsterke et signal med variabel størrelse fra en fotodiode med kapasitiv karakteristikk. Kretsen (1) innbefatter en første tilbakekoblingsbane inneholdende en spenningsstyrt variabel resistor (8) for å variere forsterkningen til forsterkeren i forhold til størrelsen på signalet for således å tilveiebringe et utgangssignal av hovedsakelig jevn størrelse. Den første tilbakekoblingsbanen inneholder også en kapasitor (7) som kompenserer for ugunstig effekter til reaktansen i kretsen bevirket av kapasitansen til fotodioden (3) og den variable resistoren (8) for å optimalisere frekvensreaksjonskarakteristikken til forsterkeren. En annen tilbakekoblingsbane innbefatter en resistor (9) med fast verdi som blir opererbar når resistansen i den første tilbakekoblingsbanen er stor for å tilveiebringe fast forsterkning av signalene mottatt fra fotodioden (3).
