Multi-slope switching circuit for switched-capacitor signal integrator

Abstract

An apparatus, including: an integrator including a first input and a second input; and a switched-capacitor, comprising: a first capacitor; a first multi-slope switching circuit coupled to a first plate of the first capacitor; a first switching device coupled between a second plate of the first capacitor and a common mode node; a second switching device coupled between the second plate of the first capacitor and the first input of the integrator; a second capacitor; a second multi-slope switching circuit coupled to a first plate of the second capacitor; a third switching device coupled between a second plate of the second capacitor and the common mode node; and a fourth switching device coupled between the second plate of the second capacitor and the second input of the integrator.
