Abstract
We present a broadband digital PLL (DPLL)-based phase modulator supporting wide frequency modulation (FM) bandwidth (BW). It compensates for the EVM degradation due to the non-uniform period of the retimed updating clock and shortens the nonlinearity calibration time of the digitally controlled oscillator (DCO) with a phase-domain digital pre-distortion (DPD) and an encoding-assisted (EA)-LMS calibration. While generating a 10MHz 64-PSK signal, the prototype can achieve -46dB EVM with less than one-tenth of the calibration samples (time) required by the prior art.
