    摘要: An apparatus for transmitting ultrasonic waves, the apparatus comprising a microchip (300) for driving a resonant circuit and a resonant circuit which is at least one of an LC tank, an antenna and a piezoelectric transducer. The microchip (300) is a single unit which comprises a plurality of interconnected embedded components and subsystems comprising at least an oscillator (315), a pulse width modulation (PWM) signal generator subsystem (329), an analogue to digital converter (ADC) subsystem (318) and a digital to analogue converter (DAC) subsystem (327).
