The architecture of the back-channel receiver employs a two-step down-conversion where the first mixing stage downconverts using the third harmonic of the local oscillator for power efficiency. The LP-65 nm CMOS receiver consumes 335 μW with a sensitivity of −72 dBm at a BER of 10−3 and data-rate of 31.25 kb/s. The radio uses a balun and a 250 kHz reference crystal as external components. The receiver uses a 1V supply voltage for analog blocks, and 0.85V for digital blocks including the local oscillator and the frequency-locked loop circuits."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Low-power receiver for FSK back-channel embedded in 5.8GHz Wi-Fi OFDM packets","description":"An ultra-low power back-channel receiver is presented that demodulates binary a FSK back-channel signal embedded in 5.8 GHz IEEE 802.11a Wi-Fi OFDM packets.
