The bipolar junction type of these devices gradually has given way to MOSFETs.
One combination of two of these devices intended to mitigate the Miller effect is a cascode amplifier, and Darlington pairs behave like single ones with approximately the product of the respective current gains. The most common current type of these devices, often employed in the (*) CMOS configuration on integrated circuits, exploits the ability of a voltage to induce a conducting channel elsewhere via field effects. The bipolar junction type of these devices gradually has given way to MOSFETs. For 10 points, name these three-terminal semiconductor devices, which amplify and switch electronic signals.
