N2 - This paper introduces an injection-locked phase-locked loop (ILPLL) with multi-phase injection and background self-calibrated. By employing multi-phase injection to enhance injection strength, the noise suppression bandwidth is extended and thus achieving low jitter. Moreover, with injection timing and pulsewidth calibration, the noise suppression bandwidth is further improved, while achieving low spur. The proposed ILPLL is fabricated in a 28-nm CMOS, achieving 152 fs RMS jitter with - 66.5dB cspur and - 247.4dB FoMjitter at 2.4 GHz working frequency. The total power consumption is 7.8 mW from 0.9 V supply voltage.
