摘要/Abstract：
为了降低胎压监测系统中胎内监测模块的功耗,采用125kHz低频唤醒通信链路实现主动监测以降低胎内监测模块的功耗,延长锂电池的寿命.125kHz低频唤醒接收机大部分时间都处于监听模式,需要对电路进行充分的低功耗设计分析.针对125kHz低频唤醒通信链路中的接收机,采用上海先进半导体有限公司(ASMC)的0.35μm 5~40VBCD汽车电子工艺设计一款低频唤醒接收机,该接收机的总面积为1.4mm2,核心面积为0.48mm2.经过流片和测试验证,该接收机的后仿真功耗为4.72μA.测试得到的灵敏度指标为0.5
In order to reduce the power consumption of tire monitoring module in the tire pressure monitoring system,adopting the 125 kHz low-frequency wake-up communication link achieve proactive monitoring to reduce tire monitoring module's power consumption to extend the life of lithium batteries.Most of the time,125 kHz lowfrequency wake-up receiver is in monitoring mode,so it is essential to take an low-power design analysis.As for the receiver in 125 kHz low-frequency wake-up communication link,adopting Shanghai ASMC's 0.35μm 5V-40 VBCD automotive electronic technology to design the low-frequency wake-up receiver,total area of the receiver is 1.4mm~2,and core area is 0.48 mm~2.After tapeout and test validation,post-simulation power consumption of the receiver is 4.72μA.Tested Sensitivity is 0.5mVpp,the maximum tested data rate is 35 Kbps,and the receiver can satisfy the tire pressure monitoring system low-frequency wake-up request.
