The shortest sequence I'm aware of is: Shift-click the component on the drawing to select it. Press Alt-Enter to open the Properties dialog. Click the Change... button (which is to the rig...

Brad Levy commented,
Connections like you are describing are usually done with clamping terminals, rather than solder. Search for "ground clamp", "copper pipe ground clamp", or "copper pipe earth clamp". I would clean ...

Jan, in DS PCB, a power plane is defined as a PCB copper/electrical layer dedicated to a particular electrical (like ground) associated with it. A shape on a regular layer is not considered a power...

It is possible to do the PCB layout without a schematic. The message you are getting "Unable to add nets because there are no net classes in this design" would normally be due to not having selecte...

Below you'll find a table I generated with a spreadsheet, showing the results of the six cascaded nodes. The green columns indicate the comparator output for each node (which drives the LOAD line/L...

By the way, for signals in this frequency range, if I needed 6 or more chained nodes of a function that didn't happen to be the same as the internal stage of an A/D converter, I'd probably still us...

Brad Levy commented,
I'm not saying you set out to design an A/D circuit. But I recognized that your nodes happen to be doing the exact same thing as stages of one method of A/D conversion do. So why not take advantage...

Doing the gain-of-2 using a second op-amp stage is a good plan. Regarding choice of op amp, there are many to choose from. Quite a few of them are low voltage, eliminating them from consideration f...

Analog switches are like electronic (vs electro-mechanical) relays.Not being mechanical, they are much faster than relays, and the control input is much lower power than a relay coil. But like op a...
