Abstract
System and method for reducing power-on transient current magnitude on distributed header switches. A preferred embodiment comprises a distributed header switch coupling a circuit to a power supply, the distributed header switch comprising a linear sequence of combination switches, each combination switches containing a pre-charge switch and a header switch. A first-pass involves sequentially turning on each of the pre-charge switches, which enables a voltage level at the distributed header switch to approach that of a final voltage level and a second-pass involves sequentially turning on each of the header switches. Since the voltage level at the distributed header switches is close to the final voltage level, a resulting transient current is small in magnitude.
