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.
