Abstract: An analog-to-digital converter (ADC) has a chopper-stabilized sigma-delta modulator (SDM). The SDM uses switched-capacitor integrators to sample, hold, and integrate an analog input in response to non-overlapping multi-phase clocks. Chopper multipliers are inserted on the inputs and outputs of an op amp in a first stage integrator. The chopper multipliers swap or pass through differential inputs in response to non-overlapping chopper clocks. A master clock operating at a frequency of the multi-phase clocks is divided down to trigger generation of the chopper clocks. Delay lines ensure that the edges of the chopper clocks occur before the edges of the multi-phase clocks. The chopper multipliers have already switched and are thus stable when multi-phase clocks change so charge injection at switches controlled by the multi-phase clocks is not immediately modulated by chopper multipliers. This clock timing increases the time available to respond to charge injection at switches improving linearity.
