Question
The base width gain in one type of these devices changes to reduction width in the Early effect. An insulating metal oxide layer may be found in a type of these devices whose three nodes are the source, gate, and drain. The bipolar junction type of these devices are contrasted with their “field-effect” type, which includes MOSFETs. By (*) Moore’s law, the number of these devices in a microchip doubles about every two years. Vacuum tubes were replaced by these devices, billions of which can be found in each computer chip. For 10 points, name these circuit components that can be used to amplify or switch electronic signals. ■END■
