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

Claim 6:
7. The system of claim 3, wherein:
the ramp bias generator comprises:
a master current source; and
a ramp bias amplifier configured to output the ramping bias voltage responsive to a ramp-reference voltage node and a feedback node, the feedback node indicating an amount of current flowing through the master current source as biased by the ramping bias voltage; and

the phased switch controller is coupled with the plurality of switches further to:
control a fourth one or more switches, during a first clock phase that includes the first time period, to pull the ramp-reference voltage node to a first ramp-reference voltage level; and
control a fifth one or more switches, during a second clock phase that includes the second time period, to output the ramping bias voltage by transitioning the ramp-reference voltage node from the first ramp-reference voltage level to a second ramp-reference voltage level over the second clock phase to produce the ramping transition profile, the transitioning driving the ramp bias amplifier to generate the ramping bias voltage to track the ramping transition profile.
