Abstract
Aspects of the present disclosure include systems, methods, devices, and circuits for fast settling of a bias node. Consistent with some embodiments, a bias circuit may include a successive-approximation-register-analog-to-digital converter (SAR-ADC) based settling loop configured to perform a fast settling process for a heavily loaded bias node. The SAR-ADC based loop performs a SAR-ADC process that includes measuring a reference signal to determine a number of cells in a capacitor array that are involved in a charge sharing process while simultaneously completing the settling process for the bias node.
