| Abstract: | Based on a discussion on the principle and essentiality of piezoelectric transducer's frequency tracking by the PLL circuit, a practical circuit for tracking the fp region is given. The effect of matching inductor and load on the circuit's tracking ca- pability was studied through experiment. The result shows that this circuit has a good performance in both frequency tracking and automatic power adjusting. |
