Abstract
A conversion circuit for converting a current signal into a first output voltage signal, where the current signal flows through a sensing component, is provided. The conversion circuit includes: a first current eliminating circuit, configured to eliminate a first current in the current signal. The first current eliminating circuit includes: a current sample and hold circuit; and a current driving circuit, coupled between the sensing component and the current sample and hold circuit; a second current eliminating circuit, coupled to the sensing component and configured to eliminate a second current in the current signal; and an integrating circuit, coupled to the sensing component and configured to integrate a third current in the current signal, and output a first input voltage signal between a first integration output terminal and a second integration output terminal.
