Abstract
Adjusting a relative phase within a polar receiver to reduce a DC error, the polar receiver having (i) a harmonic ILO having an RF modulated signal input and a phase-compressed divided-frequency output, (ii) a fundamental ILO connected to the phase-compressed divided-frequency output and having a phase-locking output, (iii) a delay element, and (iv) a phase discriminator connected to the delay element output and to the phase-locking output, and having a phase-detection output representative of a phase difference between signals on the delay output and the phase-locking output.
