Today, 12:16Consider that edge sensitive flip flops are usually implemented as master slave topology circuit.4 replies | 73 view(s) -
Yesterday, 23:21I presume the output of the shown sensor arrangement can be transformed to cartesian xyz coordinates by a linear operation. A signal that represents...3 replies | 130 view(s)

Yesterday, 11:46That's a rather trivial interpretation, only based on the external waveforms shown in the simulation. You need to look at internal voltages and...5 replies | 157 view(s)

16th January 2019, 22:25FvM replied to a thread USB differential pair on 2 layer board in Hobby Circuits and Small Projects ProblemsI have no impedance calculator at hand right now, but 40 miles trace width doesn't sound far off. It depends on the minimal clearance that can be...3 replies | 153 view(s)

16th January 2019, 10:09FvM replied to a thread MCPCB which is double sided and with plated through vias in Power ElectronicsI see that the LEDs are populating only a small part of the top side, thus a heat spreading feature may be helpful. The through plated double side...8 replies | 164 view(s)

15th January 2019, 12:48The stimulation signal timing is the same, but the required reset setup time is obviously different.5 replies | 157 view(s)

15th January 2019, 08:05FvM replied to a thread MCPCB which is double sided and with plated through vias in Power ElectronicsThanks for clarification. I didn't yet see this kind of double sided MCPCB. So they manage to isolate the vias from the metal core somehow. Two...8 replies | 164 view(s)

15th January 2019, 07:55Both simulations are different regarding DFF propagation delay and reset input setup time. We don't know which parameters you put in.5 replies | 157 view(s)

14th January 2019, 22:20FvM replied to a thread MCPCB which is double sided and with plated through vias in Power ElectronicsWhat should be the purpose of metal cladding with your board? How can it connect to a heatsink? Multilayer MCPCB can be made, although not so common....8 replies | 164 view(s)

14th January 2019, 17:33The R value is reasonable 2.2nF. Y2 capacitor won't give much snubber effect, better use X capacitor with 47 nF or 100 nF capacitance. - - -...17 replies | 368 view(s)

13th January 2019, 23:28FvM replied to a thread Spartan 6 - OSERDES2 to ODDR - Unroutable signals in PLD, SPLD, GAL, CPLD, FPGA DesignThe DDR output register is fed with half the final output data rate. This should allow to use general core registers for the 5:1 serializers. In...4 replies | 251 view(s)

13th January 2019, 23:08That's an option. It's still rather difficult to interface the SMD transistor package to a heatsink. You can e.g. use massive thermal vias and mount...8 replies | 227 view(s)

13th January 2019, 17:11You should start to design the transistor heat sinking. 150 A (27 W conduction losses in static operation) won't work on any kind of regular PCB. I...8 replies | 227 view(s)

13th January 2019, 17:00FvM replied to a thread "Crystal set" radio works only when connected to earth in Elementary Electronic QuestionsThe confusing point is the claim of using a ferrite rod antenna. If it works, radio operation won't depend on an earth connection. I guess,...5 replies | 239 view(s)

13th January 2019, 16:42It's apparently voltage supervisory application. You would specify threshold voltages for all monitored voltages, e.g. +5V >= 4.75V, -5V <= -4.75 and...17 replies | 421 view(s)

13th January 2019, 12:15R4 is effectively useless because industry standard triacs have a gate "pull-down" resistor already built in. RC filter R5 + CAP is suggested at...2 replies | 171 view(s)

13th January 2019, 11:25First point has been clarified, the Sumida datasheets give sufficient information about current rating. Second point is how to read it. Assuming...8 replies | 254 view(s)

12th January 2019, 16:42The 4 MHz "noise" can't be generated by a slow OP, it must be sourced from the µC or other circuit parts. Seeing so large interference signals raises...13 replies | 326 view(s)

12th January 2019, 15:16That's a MOV+cap combination, not a RC snubber. Please review also the circuit suggestions in AN3008 for trigger circuit RC filter.17 replies | 368 view(s)

12th January 2019, 11:33I still believe that the least effort solution for smooth DC braking is applying a low constant DC voltage (e.g. 10% of rated AC motor voltage)...29 replies | 1416 view(s)
