Claim 18:
19. The method of claim 18, wherein:
the transitioning comprises coupling the ramp reference voltage node to the second ramp-reference voltage level via a parallel resistor-capacitor network to pull the ramp-reference voltage node from the first ramp-reference voltage level to the second ramp-reference voltage level over the second clock phase in accordance with the ramping transition profile; and
the generating the ramping bias voltage comprises generating the ramping bias voltage by a ramp bias amplifier responsive to feedback control based on comparing the ramp reference voltage node and a feedback node, the feedback node indicating an amount of current flowing through a master current source being biased by the ramping bias voltage, such that the ramping bias voltage is generated so that the amount of current flowing through the master current source tracks the ramping transition profile.
