Class A amplifiers ( purely linear, with the devices always " on " ) have a theoretical maximum efficiency of 50 % and some versions have efficiencies below 20 %.
32.
The gallery shows a modern home-constructed, fully differential, pure class A amplifier of about 15 watts output power without negative feedback, using 6SN7 low-power dual triodes and KT88 power tetrodes.
33.
Class-A amplifiers generally use only one device, unless the power supply is set to provide both positive and negative voltages, in which case a dual device symmetrical design may be used.
34.
Secondly, since the klystron has beam current throughout the RF cycle, it can only operate as an inefficient class-A amplifier, while the grid of the IOT allows more versatile operating modes.
35.
John Linsley-Hood is best remembered by hi-fi enthusiasts for his " Simple Class A Amplifier ", which he developed to provide a good-quality performance comparable to that of the classic Williamson amplifier.
36.
Although grid-controlled mercury-arc valves bear a superficial resemblance to triode valves, mercury-arc valves cannot be used as amplifiers except at extremely low values of current, well below the critical current needed to maintain the arc.
37.
Klystrons are used as amplifiers at microwave and radio frequencies to produce both low-power reference signals for superheterodyne radar receivers and to produce high-power carrier waves for communications and the driving force for modern particle accelerator.
38.
Corner-lot analysis is most effective in digital electronics because of the direct effect of process variations on the speed of transistor switching during transitions from one logic state to another, which is not relevant for analog circuits, such as amplifiers.
39.
Using a variety of equipment such as amplifiers, oscillators, filters, and four-track tape recorders, the two men formed the Cooperative Studio for Electronic Music and began composing electro-acoustic music for over one hundred Space Theater performances presented between 1958 and 1964.
40.
Based on this definition, the drain efficiency cannot exceed 25 % for a class A amplifier that is supplied drain bias current through resistors ( because RF signal has its zero level at about 50 % of the input DC ).
