Abstract
A 900-MHz high-sensitivity split-channel binary
frequency-shift keying (SC-BFSK) reconfigurable data/wake-up
receiver (RX) for low-power wide-area networks (LPWANs) is
presented. In the data mode, the proposed RX demodulates
data through the RF/analog front end (RXFE), the analog-
to-digital converter (ADC), and the modulator–demodulator
(MODEM). The MODEM implemen ted in the external micro-
controller unit (MCU) applies additional digital signal processing
to improve about 17-dB sensitivity. In
