title = "62.3% Reduction of Power Dissipation and 60% Reduction of Recovery Time Caching Digital Low Dropout Regulator",
abstract = "Different from conventional digital low dropout (DLDO)regulators that adaptively respond to load changes,the proposed DLDO regulator communicates with the microprocessor to achieve fast transient response at low switching frequencies. The proposed data detection (DD) technique collects data and sends it to the cache to record the operation of the entire circuit at different drive currents. Error Quantization Control (EQC) sets adequate compensation to immediately regulate the output voltage. Therefore,compensation corresponding to different load currents can eliminate unnecessary recovery time,and limit the number of switchable power MOSFETs to one to reduce the limit cycle oscillation (LCO). The test chip fabricated in CMOS 40nm process proves the settling time reduces from 1.3μs to 0.52μs. At the same time,more than 62.3% reduction in power and 60% reduction in recovery time can be achieved. ",
