This amplifier for instrumentation with very high input impedance was found in a manual of JFET circuits. The operational ones used are current and the power supply must be symmetrical.
This project is of great use as it serves both to feed test equipment as well as to the component...
This conventional slow-moving circuit uses incandescent light bulbs, but can be changed to use...
This circuit generates sawtooth signals whose frequencies depend on the values of the selected...
