Answer by periblepsis for Adding diodes in parallel with a load

You could try something like this:I think that replicates what you are looking to get.

Answer by periblepsis for LTSpice simulation of Class AB amplifier not...

That topology doesn't really have its DC bias under much management. So there will need to be some tinkering when you build that topology (or the modified version I suggested.)Let's look at my...

Comment by periblepsis on What am I doing wrong in this transistor amplifier...

@BlackWatch You are looking to produce a power amplifier with, if you consider the required harmonics for a decent square wave to include 1X and 3X and 5X, about 1500 MHz gain-bandwidth product (48...

If you want to study the topic, there's a reasonably old but useful book for beginners called "Bebop Bytes Back: An Unconventional Guide to Computers" that would be worth some time. It really is for...

Comment by periblepsis on Uploading a Code Wirelessly to a Teensy

It just looks as thought RPi0 is using WiFi to periodically observe a dropbox account, looking for binary files that may from time to time appear there. If it finds something, it downloads it and...

Comment by periblepsis on Why doesn't wire direction affect the flow of...

In a wire, the electron doesn't see the positive terminal. It sees a charge gradient on the conductor's surface. The bent wire case is exactly the same as the unbent case, except for a very very tiny...

Badr, I did write a few things that may help on the Schmitt trigger idea. That would be for on/off control as you show. But it isn't difficult to set up a PI or PID opamp arrangement, if %-output power...

If you look at the 74LS138 datasheet you will see them provide there an inverter group for the three input lines (used as a buffer) followed by another inverter group because they need both inverted...

Comment by periblepsis on Solving this transistor circuit without using...

@dvx2718 Just as G36 suggests, via their link to an answer, you most certainly can use KVL. You first assume that the transistor is in active mode and that therefore you can assume the collector is...

Comment by periblepsis on Time constants, Transient response

thauling, An aspect of this topic is part of an answer I gave regarding a failure mode of a scope probe. Although it's not a direct answer, it may be of some use.

Comment by periblepsis on Indicator LED driver with minimal components

@user146..: Voltage-only control is a bad idea. Current is an exponential function of applied voltage. Voltage-drop variations for the same LED current, one to another, are significant, considering...

Kuro, If you drill into here, down into the Table of Contents by Hardware Driver Class section, you will see a 7-segment driver example for two digits. Have you referenced the code provided there?

Comment by periblepsis on How much power is dissipated by the resistors in...

ChatGPT is a fail. You will never really learn anything that way. (Wait at least another 4-5 years. And maybe not then.) What do you know about how to apply KVL to this circuit? Do you know how to form...

@SebastianWnęk See what you can work out and add any progress into the question. For example, if you can work out the Thevenin values I suggest are needed, then write them down. If you can't work them...

Comment by periblepsis on nMOS FETs in parallel

If you want to control color and brightness with RGB then you will need to color-balance all three, first. This means setting the current through R, G, and B, separately from each other for a 100%...

Answer by periblepsis for CE and CC cascade Amplifier

Your question is quite valid if \$R_{_\text{L}}\$ is the actual load and if a quiescent DC current is not desirable (such as with a speaker.)But the circuit, as shown, is not practical. Part variations...

Comment by periblepsis on How to set bias on an old amplifier

Anthox, The first job in understanding the circuit is to redraw it and to do so following rules found here. The process of breaking things into subsections leads not only to understanding, but also to...
