Comparator Circuits using IC 741, IC 311, IC 339
The basic function of a comparator circuit to compare two voltage levels at its input pins and produce an output to show which input voltage has higher potential than the […]
Transistor Common Collector
A BJT common collector amplifier is a circuit in which the collector and the base of the BJT share a common input supply, hence the name common collector. In our […]
