A temperature-compensated RC oscillator using temperature sensor
… This thesis introduces a practice of utilizing a temperature sensor to compensate for an RC oscillator based on FLL (frequency-locked loop), on the same die of the temperature sensor, with the assistance of a frequency counter and a computer. The TCO (temperature-compensated oscillator) and the …

Electrical characterization of high temperature superconductors as a function of temperature
… Bi 2Sr 2Ca2 Cu3010 (BSCCO- 2223/Ag) tapes at temperatures ranging from 77 K to 110 K were measured using a typical four-terminal technique for two different BSCCO-2223/Ag tapes manufactured by Vacuumschmelze (VAC). The critical currents for the two VAC samples were measured as a function of …
