摘要


隨著可攜式電子產品的發展與盛行,低功率與高效率成為可攜式電子產品設計的首要考量。基本的線性調節器因為要考慮外部較大的負載電容,會佔據較大的面積且不利於SOC環境下操作。電容式壓力感測器會受到溫度影響而產生誤差,此處提出一溫度感測器與低壓差線性調節器應用於電容式壓力感測器之讀取電路,電路系統的設計與分析是使用TSMC 0.18μm CMOS 1P6M的標準製程實現,低壓差線性調節器的輸出穩壓為1.8V、負載調節率為3.36mV/mA、最大輸出電流為5mA、含參考電壓源及之整體靜態電流49μA,輸入電壓範圍2.1V~3.5V,溫度感測器精確度為±2°C

The evolution of the portable electronic systems has driven the effort to reduce the power consumption and to improve the efficiency. The traditional linear regulator has to consider this external load capacitance, it constitute for a large area and it is not suitable for system on chip. The capacitive pressure sensor is temperature sensitive. Therefore, this study proposes are a temperature sensor circuit and a capacitance-less low dropout linear voltage regulator on readout circuit of capacitive pressure sensor device. The system is designed and implemented in the standard TSMC 0.18μm CMOS 1P6M process. The low dropout voltage linear regulator show that the output voltage is 1.8 volts, the line regulator is 3.36mV/mA, the maximum load current is 5mA, the quiescent current is 49μA containing the bandgap reference, the input voltage is ranged from2.1V to 3.5V. The temperature sensor show that the accuracy is ±2°C
