Abstract:
Embodiments relate to a chopped amplifier system where a ripple reduction filter placed outside of a main signal path is disclosed. The chopped amplifier system includes a chopped amplifier having an input terminal and an output terminal, where the input terminal receives an input signal and the output terminal provides an output signal including a ripple that is based on an offset voltage of the chopped amplifier. The ripple reduction filter is placed in a feedback loop path that receives a portion of the chopped amplifier's output signal and provides a feedback signal to the chopped amplifier that reduces the ripple at the output of the chopped amplifier. The ripple reduction filter includes a digital controller and other circuits that can handle large disturbances such as large signal slew rate events and large common-mode steps without reducing the effectiveness of the ripple reduction filter in reducing the ripple.

Claim (Index 5):
The system of  claim 3 , wherein the ripple reduction filter further comprises:\n a slew rate detector comprising an input terminal and an output terminal, the input terminal of the slew rate detector coupled to the output terminal of the chopped amplifier; and a digital controller comprising an input terminal and an output terminal, the input terminal of the digital controller coupled to the output terminal of the slew rate detector and the output terminal of the digital controller coupled to a control terminal of the variable gain sampler.
