A novel circuit for emitting and receiving ultrasound is developed in this paper. In the emitting ultrasound circuit, no high input supply is needed to generate a triggering pulse voltage up to 400 Volts. This reduces the cost and enhances the safety. In receiving ultrasound circuit, MAX4104 and TLC5540 for A/D transformation are used to make the circuit simple and practical. Experimental results show that the novel circuits can work stably with a high accuracy.
