A 2.4 GHz ternary sequence spread spectrum OOK transceiver with harmonic spur suppression and dual-mode detection architecture for ULP wearable devices
SJ Kim, CS Park, Y Kim, S Yun… - … IEEE Symposium on …, 2016 - ieeexplore.ieee.org
A novel 2.4-GHz Ternary Sequence Spread Spectrum (TSSS)-OOK Transceiver with spur
suppression and dual-mode detection architecture is presented for the ULP wearable
devices. A random bi-phase switching of a PA rejects the intrinsic spur of spread spectrum
OOK TX by 22dB. A new TSSS-OOK TX supports spreading spectrum and dual reception of
the coherent as well as non-coherent mode, implementing 12 dB SNR gain. The single-chip
TSSS-OOK transceiver in 90nm CMOS occupies an active area of 2.1 mm 2 and measures 1 …

A novel 2.4-GHz Ternary Sequence Spread Spectrum (TSSS)-OOK Transceiver with spur
suppression and dual-mode detection architecture is presented for the ULP wearable
applications. A proposed TSSS-OOK TX supports spreading spectrum and dual reception of
the coherent as well as non-coherent mode. A random bi-phase switching of 0 and 180
degree at PA suppresses the intrinsic spur of spread spectrum OOK TX. Also, both the
fractional-N Phase Locked Loop (PLL) and frequency locked loop (FLL) are integrated to a …
