This circuit is from Motorola's 1990 Linear Databook. The transistors allow equivalents and the output power depends on the supply voltage. The power supply must be 30 V symmetrical.
The circuit that gave rise to this configuration was found in a magazine of the 1980s with the...
The HA2620 integrated circuit used in this comparator is from the 80's, but the setting can be...
In the figure we have a good rectangular signals generator with several frequency bands. The...
