  • Abstract
    A 2.4GHz ISM-band PLL with a 730kHz bandwidth, a 12MHz reference, an on-chip loop filter, and worst-case phase noise of -101 dBc/Hz and -124dBc/Hz at 100kHz and 3MHz offsets, respectively, is enabled by an adaptive phase-noise cancellation technique with 35mus settling time. The 0.18mum CMOS IC measures 2.2times2.2mm2, and its core circuitry draws 20.9mA from a 1.8V supply.
