A Circuit for Reducing Large Transient Current Effects on Processor Power Grids
San Francisco, CA(2006)
摘要
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
