Bob Pease's High Impedance Active Scope Probe (PCB Design)
This project contains the passive schematic and PCB design for the circuit as simulated in `Bob Pease's High Impedance Active Scope Probe simulations`.
This project contains the passive schematic and PCB design for a simple DIY low frequency high input impedance active scope probe adapter.
It could also be used with a DVM.
First project
A simple project to demonstrate schematic capture, simulation and PCB layout
Inverting 0-20V signal from +/-15V powered opamp (simulation)
A simple simulation adapted from the [YouTube video](https://youtu.be/F9w5r5l0J8Y) by devttys0.
The problem is to invert a 0-20v signal using only an opamp powered by a +/-15V DC supply. The circuit can be broken down to three stages:
1. Shifting the signal down to be +/-10V signal > Add a 0.1uF cap which will block any DC element in the signal.
2. Inverting the signal > Use a classic inverting a...
