The function signal generating device is refers can automatically have voltage waveform the and so on the square-wave, sine wave, triangle wave instrument, it obtained the widespread application in the experiment and the scientific research. This topic duty designs a function signal generating device, enables its automatically to have the square-wave, the triangle wave as well as the sine wave. The present paper mainly aims at the function signal generating device to carry on the elaboration, it is basic may divide into four parts, the first part mainly is to some mold electricity number electricity aspects knowledge like voltage comparators which designs applies, the integrator, the differential amplifier and so on carries on the simple introduction; The second part of main content was proposed following two kind of design proposal: The first kind of plan is based on the monolithic integrated chip MAX038 function signal generating device design, the second kind of plan is based on the transistor, transports puts function signal generating device the and so on the IC design, and carries on the analysis comparison to these two kind of plans merit and the shortcoming, finally determined uses the second kind of plan to complete the function signal generating device the design. The third part specifically introduced my design proposal - based on the transistor, transports puts function signal generating device the and so on the IC design, it is this article core, did this part narrate the performance index, the functional block diagram, how as well as calculates through the parameter determines the design electric circuit and so on several aspects the content; The article fourth part mainly introduced the debugging installment method, and to designed the breakdown which appeared to carry on the brief analysis.
Key words: Function signal generating device Differential amplifier Integrator
