In Parts 1, 2, and 3 we took a closer look at calculating “ac” gain and how to desensitize the circuit to temperature and transistor parameter variations. In part 4 we consider the effects of a ...

WEST LAFAYETTE, Ind. — A hacker can reproduce a circuit on a chip by discovering what key transistors are doing in a circuit – but not if the transistor “type” is undetectable. Purdue University ...

Carbon nanotube field-effect transistors (CNFETs) exploit the exceptional electrical characteristics of single-walled carbon nanotubes to create transistors with adjustable threshold voltages, high ...

A detailed teardown of the Type-75 Geiger counter reveals the J405 tube, energy compensation shroud, and a clever ...

In this lesson, students build two circuits and explore how transistors function. When Bell Labs introduced the transistor in June of 1948, a spokesman proudly announced "This cylindrical object . . .

The following automatic battery-charger design is created with a circuit that could qualify as the simplest window comparator ever built around a single transistor (see the figure). It starts charging ...

Logic gates are fundamental components of integrated circuits, and integration strategies involving multiple logic gates and advanced materials have been developed to meet the development requirements ...

A technical paper titled “Analysis of Logic-in-Memory Full Adder Circuit With Floating Gate Field Effect Transistor (FGFET)” was published by researchers at Konkuk University, Korea National ...

New technical paper titled “Multi-functional multi-gate one-transistor process-in-memory electronics with foundry processing and footprint reduction” from researchers at Ningbo Institute of Materials ...

IBM chooses a different path from Intel, Samsung, and TSMC ...

In previous parts of this series we reviewed the basic transistor parameters that determine ac voltage gain and practical considerations limiting high gain. The role of a coupling capacitor was ...

Engineers propose a built-in security measure that would better protect computer chip hardware from hackers. A hacker can reproduce a circuit on a chip by discovering what key transistors are doing in ...
