Single-transistor graphene amplifier Researchers from the University of California – Riverside and Rice University have made the first single-transistor amplifier from graphene. The device is better ...

Abstract: The high frequency transistor equivalent circuit applicable for our consideration is shown in Figure 1. Typical values of the parameters for a state-of-the-art silicon npn microwave ...

The junction transistor may be represented as an active network in terms of various two-terminal pair equivalent circuits. The principles of design of audio-frequency amplifiers consisting of one or ...

Un transistor es un dispositivo semiconductor que puede actuar como interruptor o amplificador, dependiendo de cómo conectes sus tres terminales: la base, el colector y el emisor.

Unfortunately, driving the output signal closer to the supply rail also reduces the amplifier's linearity. This reduction occurs just as frequently at RF frequencies as it does at audio frequencies.

-Designed a circuit using BJTs while maintaining specific requirements, while testing inverting/non-inverting transistor amplification as well as single-stage and multistage amplifiers using NI ...

I am repeating his commentary here. Lou You hit the points pretty well. For a guitar amplifier tubes absolutely make a difference. The key is that they distort differently than transistors.

Reportedly, this amplifier provides the best-known efficiency in the industry for any 5:1 bandwidth amplifier over this frequency range and power level. CREE INC., Durham, NC. (919) 313-5300.
