Nested chopper delta-sigma modulator

A nested chopper circuit, comprising:

• a first chopper section, the first chopper portion coupled to input terminals, the first chopper section having two outer switches and two inner switches, the outer switches being controlled by a first non-overlapping clock and the inner switches being controlled by a second non-overlapping clock;
• and
• a second chopper section, the second chopper section being coupled to the first chopper section, the output of the first chopper section leading to an input of the second chopper section, the second chopper section having four switches being controlled by a pair of chopper clocks, the first and second non-overlapping clocks each being a multiple of the pair of chopper clocks, and first and second non-overlapping clocks being configured to invert on a period continuously, the inverting of the first non-overlapping clock being in opposite phase from the second non-inverting clock.
