Abstract
Integrator circuits comprising switched capacitors, non-switched capacitors, and an op amp. One embodiment is directed to an integrator circuit comprising an op amp having an inverting input, a non-inverting input, an inverting output and a non-inverting output, a first sampling capacitor and a first feedback capacitor, and a first non-switched capacitor. The first feedback capacitor is coupled between the inverting input and the non-inverting output of the op amp, and the first non-switched capacitor is coupled between the negative integrator input and the inverting input of the op amp. During a sampling phase, a positive integrator input is coupled to the first sampling capacitor, and during an integration phase, a charge sampled across the first sampling capacitor during the sampling phase is transferred to the first integration capacitor.
