As information security chips are more widely used in the field of information security, the security of chips becomes increasingly important, which has also been a hot research field of information security. With the advances in technology, a chip-invasive method of attack which uses laser or focused ion beam (FIB) to change the chip's internal signal line, and then probe the chip's secret information...
A low-power 433MHz transmitter is designed using 0.18um CMOS process for battery-less TPMS. It is mainly composed of a PLL frequency synthesizer and a PA, and the transmitter is achieved in a fully integrated chip except for choke and output match inductor of PA. Based on post-simulation, locked time and phase noise of the PLL are respectively about 60us and −105dBm/Hz@300kHz, the power consumption...
A 13.56MHz 3w RF power was transferred up to 43cm for Battery-less-Tire Pressure Monitoring System (TPMS) with CMOS technologies. The diameter of transmitting antenna coil for the 3W 13.56MHz Power Transmitter is 40cm, and the receiving antenna coil for the Monitoring Module is of the same size and installed inside tire. The power recovery circuit converts received RF power to DC power of 2.88V continuous...
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)...
