| Question | Answer |
| The bipolar transistor isn't the only type of transistor that can be used for amplification. Another type is the _________ (___) transistor. | field-effect, FET |
| The two major types of FETs are _____ field-effect transistors (___) and _________ field-effect transistors (____). | junction (JFET), metal oxide silicon (MOSFET) |
| There are two basic types of JFETs: ______ jfets and ______ jfets. | N-channel, P-channel |
| In a FET, the lead connected to the p-type section is called the ____. This is the control electrode, just like the base in a bipolar transistor. | gate |
| In a FET, the _____ lead is the entrance port for majority charge carriers. | source |
| In a FET, the ____ lead is the electrode that controls the motion of the charge carriers. | gate |
| In a FET, the ____ lead is the exit port for charge carriers. | drain |
| When a FET is operating, current flows in from the ____ lead, through the channel, and out the ____ lead. | source, drain |
| The term _____ is used to indicate the point when the depletion region is large enough to completely stop the flow of charge carriers through the channel. | pinchoff |
| Three methods of biasing a JFET are ________ biasing, ___________ biasing (aka ____), and ____ biasing (aka _____ biasing). | power supply, automatic gain control (AGC), source (self) |
| In _______ biasing, a DC power supply is used to provide the required negative gate voltage. | power supply |
| In a radio (or other receiver), _________ (AGC) bias is obtained by rectifying the incoming signal. The rectified voltage provides the DC voltage used for biasing. The signal is modified by other circuits before it's used to bias the JFET. | automatic gain control (AGC) |
| _____ biasing is the most popular method used to bias a JFET. | source (aka self biasing) |
| A ________ field-effect transistor (MOSFET) is a type of FET with an insulated gate lead and no PN junction. | metal oxide silicon |
| An enhancement MOSFET can be modified to be used as a _____ amplifier. To do this, the channel must be capable of producing a high source-to-drain current. | power |
| A special type of enhancement MOSFET called a _____ field-effect transistor (____) or ____ MOSFET (____) is used to amplify power. | vertical (VFET), vertical (VMOS) |
| _____ diodes are added to many MOSFET devices to prevent it from damage from static charges. | Zener |
