This Intersil circuit was found in a 1980s documentation. Operational are of the time, but current equivalents can be experienced. The graph with the circuit performance is given next to the diagram.
The circuit shown in the figure can generate signals up to 1.6 GHz. Coil L1 and capacitor C2 are...
The LM2904 is not very common today, but common comparators and operationals can be used in the...
Found in a 90s R-E Experimenters Handbook, this circuit amplifies signals from 100 Hz to 3 MHz....
