This paper presents a Class-C LC VCO which can be used for 802.11 b/g/n, Bluetooth and ZigBee. Implemented in 0.18μm process, the VCO can achieve coarse frequency tuning and fine frequency tuning. The bias voltage of the cross-coupled transistors can be adjusted to control the conduction angle of the VCO to improve the current utilization efficiency. The bias current can be adjusted to achieve a c...Show More
This paper proposes an innovative rail pressure sensor signal processing algorithm to determine the start of injection and end of injection for single or multiple injections of diesel engines with a common rail injection system (CRIS). The importance of fuel injection timing (FIT) and fuel injection volume (FIV) in the CRIS is discussed, as well as the current progress of research in this field. T...Show More
This paper presents an energy-efficient wireless transmission scheme for battery-less vehicle tire pressure monitoring system (TPMS). Our proposed transmission scheme includes a wake-up communication link with 125-kHz carrier frequency and a data communication link with 433-MHz carrier frequency. Considering the TPMS application requirements and the special nature of the vehicle environment, we de...Show More
