| Popis: | 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 2.1mm2 and measures 1 Mb/s, 22dB spur-suppressed output spectrum and 5.5% EVM at 2.17mW. |
