Abstract:
An integrator circuit with a reset mechanism, comprising:an integration capacitor; a reset capacitor; a first integration switch coupled between an input of said integrator and an input side of said integration capacitor; a second integration switch coupled between an output side of said integration capacitor and an output of said integrator; a third integration switch coupled between an input common mode voltage and an input side of said reset capacitor; a fourth integration switch coupled between an output side of said reset capacitor and an output common mode voltage; a first reset switch coupled between said input of said integrator and said input side of said reset capacitor, a second reset switch coupled between said output side of said reset capacitor and said output of said integrator; a third reset switch coupled between said input common mode voltage and said input side of said integration capacitor; and a fourth reset switch coupled between said output side of said integration capacitor and said output common mode voltage, wherein said integration switches are closed during an integration mode and open during a reset mode, and wherein said reset switches are closed during said reset mode and open during said integration mode.
