Classification: CPC G | IPC G

Claim 13:
14. The system of claim 12, wherein each ith instance of the discharge stage comprises:
a first current source and a second current source, each biased by a bias voltage; and
a chopper having a first input coupled with Vin_i via a first discharge current path, a second input coupled with an (i+1)th instance of the Vin node via a second discharge current path, a first output coupled with the first current source, and a second output coupled with the second current source,
wherein the chopper is configured to toggle between a pass-through configuration and a swapped configuration at a rate controlled by a chopping clock, the pass-through configuration coupling the first input with the first output and the second input with the second output, the swapping configuration coupling the first input with the second output and the second input with the first output.
