چکیده انگلیسی
We investigated the temperature dependence of the applications of piezo PZT ceramic resonators down to 93Â K in oscillators and filters circuits inside a frequency range of 400Â kHz-4.0Â MHz. For both systems, their waveforms were plotted at different temperature values ranging from room level (293Â K) down to (93Â K). From which, it is clearly shown that, cryogenic temperature effect on the operation of the trap filter system was shown to increase the voltage value at stop-band from 1.40Â V, measured at 293Â K, up to 4.40Â V. The rise and fall times of the square wave oscillator were shown to increase slightly with temperature decreasing. Initial values of 92.3Â ns, and 85.8Â ns, measured at 293Â K, were observed to increase up to 106Â ns and 107Â ns, measured at 93Â K, respectively, while the signal output was kept constant. But for the sine-wave oscillator, its frequency, and output voltage were shown decrease as the temperature decreases
