This paper presents a fully integrated millimeter-wave phase-locked loop (PLL) frequency synthesizer fabricated in 130nm BiCMOS technology. It comprises a self-buffered voltage controlled oscillator (VCO) tunable from 29.4 to 33.0 GHz, which corresponds to 11.5% tuning range. The VCO contains a programmable binary weighted varactor bank for phase noise reduction due to configurable low VCO gain. A programmable 4-bit charge pump (CP) was designed in order to compensate for VCO gain variation. It provides fast switching and shows low mismatch between UP and DN currents. The measured phase noise of the PLL is −85 dBc/Hz and −100 dBc/Hz at 150 kHz and 1MHz offset from the carrier, respectively. The circuit draws 60mA from 3.3 V supply. It is demonstrated that the presented chip can be successfully used in FMCW radar applications.
