Current-starving in tunable-length delay (TLD) circuits in adaptive clock distribution (ACD) systems for compensating voltage droops in clocked integrated circuits (ICs) is disclosed. Voltage droops slow propagation of signals in clocked circuits. However, clock delay circuits in a TLD circuit increase a clock period by increasing a clock delay in response to a voltage droop. In large power distribution networks (PDN), impedance can delay and reduce the magnitude of voltage droops experienced at the TLD circuit. If the voltage droop at the TLD circuit is smaller than at the clocked circuit, then the clock period isn't stretched enough to compensate the slowed clocked circuit. A current-starved TLD circuit starves the clock delay circuits of current in response to a voltage droop indication, which further increases the clock signal delay, and further stretches the clock period to overcome a larger voltage droop in clocked circuits in other areas of the IC.
