This circuit is from Motorola's 1990 Linear Databook. We can implement it with other operational amplifier. The power supply must be symmetrical.
A rectangular signal applied to the input of this circuit becomes a negative pulse, which...
This circuit was found in a 1980 publication, but it can be assembled using a BD135 for Q1 or even...
This circuit, suggested by Sylvania in a 1956 publication, serves as an experimental stage for a...
