Abstract

A wide capture range PLL with low phase noise is proposed and analyzed The PLL incorporates a LC voltage-controlled oscillator (VCO) to get low phase noise while the divider is controlled by low pass filter (LPF) voltage to achieve wide capture range. The proposed PLL is designed based on the SMIC 0.18-μm 1P5M CMOS process with a 2.5V supply voltage. H SPICE simulation shows that the output frequency of proposed PLL alternates from 0.3GHz to 1.4GHz, and the phase noise is below - 120dB at a 300KHz offset from VCO center frequency.
