decoupling cap use on reg cct is basically to avoid oscillation.
But, other than this, it used to filter out the high freq noise.
Normally, there are 2 types of capacitor using at the reg output for decoupling purpose:
1. ceramic capacitor (non-polarity, smaller capacitance--> abt 1uF or less)...
My problem: Can anybody help me to find out the Cut-Off frequency and th Gain of the Op-Amp LPF as shown below? Thanks for your help.
Thanks everybody, thanks for your contribution on solving my problem. As suggested, i think i better work it out by using PSpice..
For the unit of the...
