Hello all,
I have some basic questions regarding capacitor and switch behavior.
Lets say Gate voltage of a transistor is 3.3V and I have bypass capacitors at the gate which makes 5uF in total(parallel connection).
Q = V. C (3.3V* 5uF) = 16.5u Coulomb charge is necessary to charge this C.
And I need to say switch on/off the PA with 100Hz rate, so that makes 16.5*2 of charge and discharge( so thats sink and source, a FET is needed)
33uC/10mSec= 3.3mA of current needed to charge up and down Is my calculation correct?
Best Regards,
