摘　　要：超声波发生器根据应用场合的不同,而要求有不同的电路设计方案,文章作者设计了一款应用于半导体焊线设备的超声波发生器的信号源电路,该电路采用英特矽尔公司生产的icl8038芯片,利用该芯片设计了一款高精度的波形发生器,通过选择不同电阻,电容等外部元器件,其设计的频率范围可以从0.001Hz到300KHz,并且也可以通过外部电压的扫描来产生不同频率的波形。文章作者用Proteus仿真软件对ICL8038芯片所设计的信号源电路进行了仿真。Ultrasonic generator according to different applications, and requires a different circuit design, the authors designed a applied in semiconductor welding line equipment of ultrasonic generator signal source circuit, the circuit adopts the Internet silicon, the company produces the icl8038 chip, using the chip designed a high precision waveform generator, by selecting different resistance, capacitance and other external components, the design of the frequency range can be from 0.001 Hz to 300 KHz, and also can be produced by external voltage scanning waveform of different frequency. The authors use Proteus simulation software of ICL8038 chip design has carried on the simulation signal source circuit, the desired results.
