A Coupled-RTWO-Based Subharmonic Receiver Front End for 5G E-Band Backhaul Links in 28-nm Bulk CMOS KU Leuven
© 1966-2012 IEEE. An E-band direct-conversion subharmonic receiver (SHRX) is designed exploring a coupled-rotary-traveling-wave-oscillator-based (coupled-RTWO-based) architecture. Distributed oscillators are leveraged to generate N=8 differential phases at fLO=fRF/4. Current-mode passive mixers (MXs) are adopted to enable <1-V supply operation and greatly simplify the layout. An inductively degenerated neutralized common source (DCS) ...
