Today, 09:23Hi, I don't think it's a compiler problem when the microcontroller takes 300 mA. I rather think there is a hardware problem. Klaus If you...2 replies | 36 view(s) -
Today, 06:54KlausST replied to a thread Output Resistance of Amplifier with Feedback ( Series - shunt) Loading in Analog Integrated Circuit (IC) Design, Layout and FabricationHi, I didn't take R1 and R2 into account because of the "open loop" statement. But for sure to get "open loop" you may use the R1and R2, but...3 replies | 104 view(s)
