Can you guys help me on the following question
What is the relation between a postive feedback resistor and the schmitt trigger bandwidth ? why ?
 

Re: Do youknow this ?

Since gain Bandwidth product is constant .i.e.

Gain*BW=C
Now if we increase gain (positive feedback) BW will be less. Also positive feedback is prone to oscillations.
