    Max Current and Shorted Current

    Of course there are the parts that use foldback current limiting to manage that. As well as thermal limiting monitoring die temp as well.

    JK Flip-Flop Toggles Twice from One Button Press

    RC approaches, without using a Schmidt trigger gate or comparator with hysteresis can generate problems due to excessive rise and fall times associated with the C charging. And hanging a large C off a cmos input pin can cause potential damage to cmos input structure during supply collapse on...

    Max Current and Shorted Current

    No Rl does not have to be 0 to force Q2 to rob Ibase of Q1. It just has to be a value that hits the Ilmax you calculated. If it did go to 0 then V + - V- = 5.1 (Vz). The action of the current limit outside OpAmp operates independently of OpAmp also trying to force more Ibase into Q1 as Rload...

    Buck converter calculation does not match with LTspice results

    A 1N914 is a small signal diode, so validity of your results would be in question in this type of application.

    Analysis of Op-amp circuit

    With - fdbk there is a virtual ground between + and - OpAmp inputs, so not sure why its there. However there is an input offset present, with drift, but not sure this is what your are seeing. Maybe examine model to see if input offset is dependent on time or are you just seeing the finite...

    Opamp circuit clarification

    Yes, keeping in mind the signs of the two solutions matter and - Replace all voltage sources with short circuits (wires) Replace all current sources with open circuits (breaks)

    Opamp circuit clarification

    No not the sum, as shown its 1.65633 volts. Take a look at videos on how to do superposition, very simple.

    Opamp circuit clarification

    You are running a transient solution, 10 mS, is the OP747 settled yet given the internal compensation C and other miller effects of bias generators and the like ? Not sure....

    Opamp circuit clarification

    I get the following - The NSC datasheet shows - The markers closest to opamp inputs are current measuring, all the others V. You are seeing offset and bias currents causing offsets flowing the 660K ohm R's

    What is your honest take on the "Stamp-Sized" Dev Board trend? (Xiao, QT Py, etc

    Using ESP32-C3 super mini and ESP32-S3 super mini for internet sensor client nodes to serve data to a central ESP32 server serving web page. Love them, especially S3 as its dual core.

    New to Arduino & ESP32

    A fast way of programming is block languages, like Tuniot (C++) or MPYblockly (Micropython) or Flowcode (C++). Takes GUI block configurations and generates code from them. Great for visual learners. Once you learn one its easy to use others as they each have common and specific capabilities...

    Calculation of Gate Resistance

    Show a pic of your probing/prototype/layout. Your probe ground lead real short...? If thats the case simply raise the gate R. Post schematic of driver and MOSFET wiring/layout. That MOSFET super high C so challenging for sure. That gate drive waveform, scope not set for 10X probe ? The...

    Calculation of Gate Resistance

    We are always dealing with non-exact models, hence the calculations, for the non-exact model, can meet all our rules on Thevenin's rules for analyzing circuits, but the model being inexact gives us approximations. Much of the time we can use the approximations and move on, but there are times in...

    Calculation of Gate Resistance

    The calculation gives you a non optimal value as trace Z, especially the L, and device to device variations produce a non optimal value. But as always] its a best effort compromise. In one off designs some folks trim them.
