Adam2014 Member Sep 4, 2014 #41 the ratio not constant and the output not stable for values above 10nf
alec_t Well-Known Member Most Helpful Member Sep 4, 2014 #42 Sounds like you might need a look-up table to handle the ratio, and averaging to handle the instability.

Adam2014 Member Sep 26, 2014 #43 depending on this figure https://www.rfcandy.biz/communication/pic/lcimpsch.gif what the difference between AC coupling/decoupling reactance ? is ac decoupling connected to ground ?

Adam2014 Member Sep 26, 2014 #44 as same figure #43 how c6 charge and discharge ? and where ? what its initial charge ?
Adam2014 Member Sep 26, 2014 #45 how does R10 , C10 integrator work ? it's output is 2.5 volt so i can replace it with voltage divider ? Last edited: Sep 26, 2014

alec_t Well-Known Member Most Helpful Member Sep 26, 2014 #47 what the difference between AC coupling/decoupling reactance ? Click to expand... For a capacitor, reactance is the cap impedance as given by X=1/(2.pi.f). In the schematic linked to, C1/2/3 are decoupling cap examples and C9 is a coupling cap. is ac decoupling connected to ground ? Click to expand... Usually. how c6 charge and discharge ? and where ? Click to expand... Charge and discharge is via connected components, e.g. C9, L1, Cx etc, and internal leakage. what its initial charge ? Click to expand... Probably close to zero Coulombs when the power supply is absent.
