A 60 GHz Carrier Recovery Circuit in CMOS 28nm FD SOI for BPSK/QPSK PLL-less High Data Rate Receivers

This work presents an integrated circuit fabricated in CMOS28nm FDSOI that extracts the carrier frequency of a 60 GHz band BPSK/QPSK modulated signal. The carrier extraction is operated by on chip analog signal processing which removes the modulation and regenerates a pure sine-wave oscillating at the received signal carrier frequency. The circuit consumes 45 mW from a 0.8 V supply. Furthermore, the received high data-rate signal is demodulated using the recovered carrier with an external mixer and a sampling scope without any further digital processing. The circuit shows a carrier recovery and demodulation capability up to 22 Gbps QPSK signal with 20% error vector magnitude (EVM).
