Abstract:
An ultra low-power digital baseband (DBB) for Wake-up Receiver (WuRx) is presented. Based on low power microcontroller (MCU), the DBB power gates the WuRx peripherals to further reduce their average energy consumption. It issues low duty-cycling signals with very short power-on periods, allowing very low latency between a transmitted WuPt and its detection. The latency and power consumption tradeoff can be adjusted to meet different application requirements. The presented circuit implements low-power listening protocol as a duty-cycle scheme and also emphasizes the possibility to decode more than 512-bit address pattern.
