Today, 07:15KlausST replied to a thread Transimpedance amp for DC only (bandwidth limited) in Analog Circuit DesignHi, No. Only the leakage of the capacitor may cause problems.. Use high quality polystyrene, if possible. * The diodes are for...9 replies | 146 view(s) -
Yesterday, 07:55Hi Please confirm that you talk about current harmonics (and not voltage harmonics). (The difference is, that with "current" you simply can focus...11 replies | 757 view(s)

Yesterday, 07:34KlausST replied to a thread Operational amplifier driving capability test in Analog Integrated Circuit (IC) Design, Layout and FabricationHi, I don't expect a 5% voltage drop on a non saturated, feedbacked OPAMP. Thus I expect the test setup was either in "non feedbacked"...11 replies | 213 view(s)

17th September 2019, 23:30KlausST replied to a thread Operational amplifier driving capability test in Analog Integrated Circuit (IC) Design, Layout and FabricationHi, What happens on overcurrent? Is the output weak, an thus the output voltage drops? Or is the ouput strong and the Opamp overheats? Klaus11 replies | 213 view(s)

16th September 2019, 06:27KlausST replied to a thread Li-ion Battery charger need help in Hobby Circuits and Small Projects ProblemsHi, What exactly does the datasheet say? 1C is typical or recommended charge current, or maximum charge current? (Why don't you post a link to...4 replies | 200 view(s)
