Today, 08:26FvM replied to a thread Magnet core inductor out of TV set, what is is used for? in Analog Circuit DesignThe photo in post #7 seems to show a simple coil with ferrite core. Are you sure that it involves a permanent magnet? Due to the open magnetic path,...13 replies | 274 view(s) -
Today, 08:16FvM replied to a thread Stuck at simulations of Amplifier in LTSpice in Analog Integrated Circuit (IC) Design, Layout and FabricationCapacitors are zeroed during initial transient solution, thus a SPICE simulator has no problems with large capacitors, as long as the large signal...4 replies | 250 view(s)
