发明名称 | Ultrasonic driver | ||
摘要 | An ultrasonic transducer that can include a driver side and a bias voltage side. A higher voltage source can be electrically connected to the bias voltage side through a first resistor. A lower voltage source can be electrically connected to the driver side of through a second resistor. A field effect transistor or other suitable switch can be included, having a source, a gate and a drain. The source can be electrically connected to ground and the gate can be electrically connected to a control signal source. The drain can be electrically connected to the lower voltage source through a second resistor and be electrically connected to the driver side of the ultrasonic transducer. The gate can be electrically connected to a signal source through a third resistor. | ||
