Q:

我們RD在使用Simplis時, 有遇到一個使用AND gate的problem,

如下所示, 再請幫忙釐清可能的原因?

謝謝!

Dear Alvin,

I got a problem when I simulate PWM in Simplis.

The output of an AND directed to gate of MOSFET was incorrect with regard to its inputs.

Could you help figure it out?

針對AND gate問題，工程師因為找不到廠商三隻腳的AND gate，所以提供2隻腳的AND gate的方法，請您協助參考
