180TSMC_PFD_04 is a phase-frequency detector (PFD) forms control signal for VCO tuning. PFD compares phases of divided VCO signal and divided reference oscillator signal and detects phase difference. ...

This PLL can accomplish faster phase lock. Additionally, the functions of frequency comparator and phase detector have been improved and are well synchronized. A digital controlled oscillator (DCO) ...

Traditional microscopy often relies on labeling samples with dyes, but this process is costly and time-consuming. To overcome these limitations, researchers have developed a computational quantitative ...
