Abstract

Dynamic Power Management (DPM) is a technique to reduce the power consumption of an electronic system by selectively shutting down idle components. In this paper, a DPM methodology is proposed for managing the power consumption of System on Chip (SoC) in batteryless TPMS. The main circuit adopts three power regulators to supply the IP cores (CMOS Temperature Sensor + A/D + MCU + 433MHz Data Transmitter) working voltages which are supervised and compared with reference voltage by comparators. Then the three parts are daisy-chain-connected to manage the power sequence. The power consumption is 474μW to 825μW by simulation.
