| 1. | Power electronic devices may be used as switches, or as amplifiers.
|
| 2. | It is possible to construct non-Foster networks using active components such as amplifiers.
|
| 3. | :You will need to design a Class A amplifier with resistors to define gain.
|
| 4. | Electronic feedback loops are used to control the output of electronic devices, such as amplifiers.
|
| 5. | Class-A amplifiers set their output transistors to be operated in their most accurate, and most inefficient, range.
|
| 6. | Another application is in DC class-A amplifiers.
|
| 7. | A class-A amplifier, by contrast, must use a device capable of dissipating several times the output power.
|
| 8. | This is especially needed with non-class-A amplifiers.
|
| 9. | Class-A amplifiers measure best at low power.
|
| 10. | A " class-A amplifier " is distinguished by the output stage devices being biased for class A operation.
