Abstract
A circuit that reduces power supply transients by controlling the frequency ramp between the initial and final operating frequencies of a microprocessor is presented. This is accomplished by periodically ´masking´ clock pulses to incrementally increase or decrease the average clock frequency until the final clock frequency is reached. This circuit is implemented in a 90nm partially-depleted SOI technology
