[LTspice] Triangle Wave

LTspice doesn't have the  "Triangle Wave" option, so we use "PULSE" option to generate triangle wave. See the link below for more details.

Reference:

Example:
Generate a triangle wave with low level 6V and high level 10V. Frequency= 1kHz

[LTspice] 模擬 Operation Amplifier 元件

點選工具列上的Component按鈕

輸入需要的op amp model
這邊以LT1001為例，點選之後按OK，就能在畫面擺放所選的op amp


也能在輸入的地方打 opamp
LTspice會切到C:\Program Files (x86)\LTC\LTspiceIV\lib\sym\Opamps底下
就能看到所有的op amp model了
