Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 2:
3. The system of claim 1, wherein the discharge stage comprises:
a bias generator to generate a bias voltage based at least on bias feedback; and
a rotator having: M source ports, each coupled with a respective one of the M current sources; a feedback port coupled in feedback with the bias generator; and a drain port coupled with the Vin node via a discharge current path,
wherein the rotator is configured to iterate sequentially through the M configurations, generating, for each mth condition of the M conditions: the bias feedback at the feedback port based on an mth current source of the M current sources; and the Iout based on the sum of currents through the M−1 current sources other than the mth current source.
