Abstract: Certain semiconductor processes provide for the use of multiple different types of transistors with different threshold voltages in a single IC. It can be shown that in certain ones of these semiconductor processes, the speed at which high threshold transistors can operate at decreases with decreasing temperature. Thus, the overall processing speed of an IC that implements high threshold transistors is often limited by the lowest temperature at which the IC is designed (or guaranteed) to properly function. Embodiments of a system and method that overcome this deficiency by “pre-heating” the IC (or at least portions of the IC that implement the high threshold transistors) such that the IC can operate at a frequency (once pre-heated) higher than what would otherwise be possible for a given, minimum temperature at which the IC is designed (or guaranteed) to properly function at are provided.

The control circuit maintains the level of the second pin at the second level when a voltage of the first pin is equal to a pre-determined voltage.

Abstract: A power management system permits a small microcontroller subsystem or low power domain to continuously operate while a main subsystem domain is cycling from power on to off. The power management system supports asynchronous domains with common shared peripherals. The asynchronous domains operate as a single entity while in a full power mode with the peripheral and system resources being shared. The system can be used in automotive systems where most of the system is power-gated leaving just a power regulator controller, some counters and an input/output segment alive for wakeup purposes.
