I am using the follow battery as power supply:
The circuit demands a constant current of 0.01 mA until an interrupt happens where the current demand varies from 18mA up to 90mA for 4 seconds.
I have read that "In power supplies, capacitors are used to smooth (filter) the pulsating DC output after rectification so that a nearly constant DC voltage is supplied to the load".
Is it correct to say that filtering capacitors on power supply is similar to decoupling capacitors? As i can understand both techniques has the same benefits, right?
I am sure there is a way to calculate the capacitor value exactly, but is there any common values for 3.6 volt batteries on these current demands? (like decoupling capacitors).
For an example i have device that uses the same battery as i do, and they used two parallel capacitors 1F each. Moreover, i can make a guess that the current consumption will be increased if i use capacitors after the power supply.
Is there any other disadvantages on using them?
