  • The conductivity of lead oxide doped potassium chloride single crystals

    Creator:
    Knepp, Donald Jack
    Abstract:
    A comparison was made of the d.c. conductivity of KCI:Pb²⁺ and KCl:PbO single crystals at temperatures greater than 325°C. The energy of activation was 0.72 ev for all crystals. Lead concentration was determined by chemical, optical and electrical methods. The half band width of the UV absorption band at 273...

    absorption band at 273 nm was 0.082 ev for both crystal sets although the oscillator strength in KC1:PbO

  • An ultra low power frequency reference for timekeeping applications

    Creator:
    Oporta, Hector Ivan
    Abstract:
    An ultra low power crystal oscillator that provides a frequency reference for battery powered timekeeping applications is presented. An amplitude control circuit is employed to ensure that minimum current is consumed. A subthreshold voltage regulator provides a supply voltage for the oscillator with minimum current consumption. The oscillator and regulator...
