The recent EDN article of Bruce Trump () on the input impedance of an op-amp circuit took into account the single-pole roll-off of its loop gain. He showed with a simple derivation how the equivalent ...

The bipolar junction transistor (BJT)-pair emitter-coupled differential-amplifier circuit is a familiar amplifier stage in the repertoire of analog designers, but has an interesting complication. This ...

Researchers from the University of California – Riverside and Rice University have made the first single-transistor amplifier from graphene. The device is better than conventional amplifiers thanks to ...

Graphene has already brought us the world's smallest transistor – twice – and now the one atom thick form of carbon that recently won its discoverers the Nobel Prize has been used to create a ...

THE properties of the amplifier to be described are entirely due to the type of transistor used, and the purpose of this communication is to report on its suitability for the amplification of ...

This monograph is concerned with the application of transistors to the audio-frequency amplifiers employed in sound broadcasting for which a high standard of performance is required. The prinicples ...

Back in the '60s, there was an intriguing circuit article titled "Starved-Circuit Amplifier" published in Popular Electronics magazine. It used a sharp cut-off pentode with a 3-MO load resistor and ...
