[0002] In modern society, in the design, debugging and electronic test process of signal processing, communication field and automation control system, sine wave signal, rectangular wave signal and triangular wave signal are often required as signal source or other purposes, and automation Technology has already penetrated into various fields of social production. Signal generators with high precision, wide frequency and high stability play a vital role in improving and improving the performance of the overall system. Traditional function signal waveform generators such as 8098 etc., usually made of discrete components such as transistors and op-amp ICs. The function generator composed of discrete components has a simple structure and is easy to manufacture, but it is usually a single function generator with a low frequency and a single output waveform. Output a variety of waveforms, and the output signal has disadvantages such as poor frequency linearity, low frequency stability, low frequency resolution, relatively long frequency conversion time, and large phase noise.
