It includes the design of self-calibration all-digital PVT sensors, MTCMOS switched capacitor (SC) DC-DC converter, temperature compensation for low-voltage digital assist PLL, and dynamic voltage and frequency scaling system. The major contributions are as below: 1. A near-/sub-threshold all-digital process, voltage, and temperature sensor is proposed and integrated to the DVFS control for micro-watt system applications. The sensor is proposed for high accuracy, ultra-low voltage, low power, and self-calibration portable applications. 2. A self-calibration near-/sub-threshold all-digital temperature sensor with adaptive pulse width generator is proposed. The sensor is proposed for high accuracy, ultra-low voltage, low power, and self-calibration portable applications. iv 3. A PVT-aware DVFS for micro-watt system is proposed. The system through the switched capacitor (SC) DC-DC converter can provide a very stable DC power supply. It generates different voltage levels which are suitable for SoC integrated regulator applications. 4. A novel connect scheme for improving power efficiency and reducing voltage variation of switched capacitor (SC) DC-DC converter which generates ultra low voltage is proposed. 5. Proposed a temperature compensation for low voltage digital assist PLL can modulate output frequency via divider. Use the temperature sensor to compensate the frequency can not lock in the worth case. 黃威 2010 學位論文 ; thesis 115 en_US |
