Abstract

LM566 is a monolithic integration VCO chip of integral-Schmitt Trigger Circuit type. It is the modulator and demodulator in teaching of FM circuit. Its operating features can be displayed vividly on software platform through simulation the chip to facilitate quantitative analysis. As there is no model for LM566 in component library, basic component models existing Multisim component library are used to constitute internal structure of LM566 chip to solve the problem. By analyzing static operating mode and dynamic operating mode of peripheral FM circuit, simulation result and testing result indicate that chip model in the thesis can objectively describe the basic characteristics of LM566, which lays the foundation for simulation analysis of all functional circuits including FM circuit via the chip and effectively extends application scope of Multisim simulation software. It has great application value.
