Today, 16:24It depends. Some thermal pastes with high thermal conductivity are metal filled and also electrically conductive. But as far as I can see from the...24 replies | 577 view(s) -
Today, 13:58FvM replied to a thread AMS simulation of D-FF in Analog Integrated Circuit (IC) Design, Layout and FabricationThere's no clock signal fed to your circuit, respectively output is uninitialized.. Confusingly you are providing a multi level ("electrical")...2 replies | 83 view(s)

Today, 12:59The order of magnitude sounds reasonable. Obviously the numbers have been empirically validated, but your antenna geometry may be different. You...8 replies | 332 view(s)

Yesterday, 15:10FvM replied to a thread Is there possibility to force a filter topology in DA_LClowpassMatch in ADS? in RF, Microwave, Antennas and Opticsfrdm90 didn't yet release a matching bandwidth specification. I presume, it's not possible to achieve a higher bandwidth with LC network for the...24 replies | 691 view(s)

Yesterday, 13:53Besides unsuitable probe connection it may be dropping DC supply. I won't care about it much. Overshoot is much more a problem. It probably kills the...24 replies | 577 view(s)

Yesterday, 11:56No. I referred to the isolation capacitance, e.g. the transformer interwinding capacitance. The linear voltage regulator circuit is O.K. But it's not...24 replies | 577 view(s)

Yesterday, 09:48There's no DC bus in a "direct converter", which constitutes already some of the circuit problems. It's not clear where you measure the "IGBT...24 replies | 577 view(s)

14th September 2019, 11:46FvM replied to a thread Problem adding reset to master slave D-FF for phase detector in ASIC Design Methodologies and Tools (Digital)I don't understand what you consider "wrong" in the posted simulation waveforms. I don't recognize missing pulses or similar artefacts. Please...3 replies | 238 view(s)
