915MHz Ultra Low Power Receiver using Sub-Vt Active Rectifiers
نویسنده
چکیده
A 98nW receiver with a 23nW active rectifier RF front-end biased in deep subthreshold near the saturation/linear boundary is presented. An on-chip voltage reference and 28nW hysteretic comparator are also designed using subthreshold techniques. The receiver can demodulate an OOK signal at 100kbps with a sensitivity of -41dBm and all processing for process and mismatch is handled on-chip [1]. The ultra-low power receiver is used for wireless sensor node applications, specifically for nodes that are to be worn on the body.

متن کاملA ReRAM-based non-volatile flip-flop with sub-VT read and CMOS voltage-compatible write
The total power budget of Ultra-Low Power (ULP) VLSI Systems-on-Chip (SoCs) is often dominated by the leakage power of embedded memories and pipeline registers, which typically cannot be power-gated during sleep periods as they need to retain data and program state, respectively. On the one hand, supply voltage scaling down to the near-threshold (near-VT) or even to the sub-threshold (sub-VT) d...
