Abstract:
This paper describes a -99dBm sensitivity, 260nW 434 MHz ISM band wakeup receiver (WuRX) in 65nm CMOS without MEMS filters, which is 18dB better sensitivity than any prior MEMS-less sub-μW design. The WuRX supports a new Channel-Embedded OOK single-tone TX scheme to enable multichannel operation without a local oscillator, improving usability for long-range, high density IoT applications. Reconfigurable within-bit duty cycling of the tuned-RF front end trades power for latency between 260ms latency at 2.17μW and 2.6s latency at 260nW.
