Abstract (en)
The switch has a transistor (1) connected between input and output terminals of a circuit. The input terminal receives a positive supply voltage, while the output terminal is connected to a load (Q). A transistor (2) is connected between the input terminal and an input of a current mirror circuit thorough a bias circuit (6) that acts as an output voltage follower of the switch on a collector of the transistor (2).
