  • Abstract
    A 0.18 μm CMOS fifth-order harmonic-rejection GmC filter is presented for use in offset PLL transmitter applications. Using an in-situ calibration scheme with a tuning accuracy of 2% and a maximum calibration time of 90 μs, this filter tunes from 52 to 151MHz and draws 7mA from a 1.8V supply while achieving an IIP3 of 7dBV with an output noise floor of 9.3 μV in a 30kHz BW.
