Abstract
The ultrasonic wave converter, digitally controlled, is designed by sampling the high frequency ultrasonic waves. The conventional ultrasonic circuit is composed of oscillation circuits in analog mode. The oscillation circuits can be categorized into two groups i.e., (1) the that generates the fixed frequency regardless of the change of the loads, (2) and the other that controls power and the frequency by changing the voltage and current following the oscillating conditions of oscillators. These circuits are used to fix the frequency of PLL (phase locked loop). The circuit that produces the fixed frequency should select the proper frequency and the power circuit to supply the operating currents. The circuit supplies the frequency with the range of resonance frequency (about the frequency of parallel resonance frequency or the frequency of minimum impedance) and the antiresonance frequency (parallel resonance frequency of maximum impedance).
