场效应管知识点繁杂，是模拟电子技术教学的难点。本文从场效应管的结构符号

FET complex knowledge, is the difficulty of analog electronic technology teaching. From the structure and type of symbol FET, the FET characteristic curve, FET amplifier circuit with several aspects of the method set forth in the teaching process transistor contrast, can make things simple variant, to improve the teaching efficiency, increase student learning initiative, to achieve a multiplier effect.

Field effect tube knowledge point is complicated, is the difficulty of simulating electronic technology teaching. In this paper, the structure symbol and type of field effect tube, the characteristic curve of field effect tube, field effect tube amplification circuit and other aspects of the method of comparison with the tripole to explain the teaching process, can simplify the complexity, improve the teaching efficiency, increase the students' learning enthusiasm, to achieve the effect of doing more with less.

The knowledge points of FET are complex, which is the difficulty of analog electronic technology teaching. In this paper, we use the method of comparison with triode to explain the teaching process from the structural symbols and types of FET, the characteristic curve of FET, the amplification circuit of FET, etc., which can simplify the complexity, improve the teaching efficiency, increase students' enthusiasm for learning, and achieve the effect of half work.<br>
