This paper presents a Low power phase frequency detector with charge pump for low power phase lock loop. The phase frequency detector with dead zone compensation has been proposed. The paper contains the detailed circuit diagram of PFD and charge pump with 1.8v power supply and 500MHz input frequency. The design has been realized using 0.18um CMOS technology. Keywords— Low Power, PLL, PFD, CP
The local potential at domains on ferroelectric surfaces results from the interplay between atomic polarization and screening charge. The presence of mobile charge affects surface domain configuration, switching behavior, and surface chemical reactions. By measuring the temperature and time dependence of surface potential and piezo response with scanning probe microscopies, thermodynamic parame...
Zirconia is a relatively new material with many promising practical applications in medical imaging, biolabeling, sensors, and other fields. In this study we have investigated lanthanide and niobium doped zirconia by luminescence and XRD methods. It was proven that charge compensation in different zirconia phases determines the incorporation of intrinsic defects and activators. Thus, the struct...
