Reconfigurable Ge Transistors Enabling Adaptive Differential Amplifiers

Abstract: Exploiting the capabilities of multi-gated transistors is a promising strategy for adaptive and compensative analog circuits. Typically, reconfigurable transistors, which can be switched ...

Neural DSP models John Mayer’s entire amp and effects rig—and it sounds great

So do we really need one amp sim package? Neural DSP thinks we do, because the Finnish company just dropped a major new ...

Not Your Usual Analog Electronics Course—Generalized Analysis of Single-Transistor Amplifiers Uncovers Hidden Reciprocities and Equivalences

Abstract: We present a compendium of generalized expressions for the low-frequency voltage gain and terminal impedances of each of the three fundamental bipolar-amplifier topologies (i.e., common ...
