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.
Suggested by Texas Instruments in 1968 documentation, this circuit uses components from the era....
I found this circuit in an article in a 2003 publication. The circuit is an example of how to...
This configuration makes use of an LM3900 transconductance operational amplifier. The transistor can...
