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 ...

Sometimes I wish FETs had become practical before bipolar transistors. A FET is a lot more like a tube and amplifies voltages. Bipolar transistors amplify current and that makes them a bit harder to ...

Analog circuit design using MOS transistors represents a dynamic and rapidly evolving field that is integral to modern electronics. Exploiting the inherent advantages of MOS technology—such as ...

As you probably know, processors – and most other digital technology – are made up of transistors. The simplest way to think of a transistor is as a controllable switch with three pins. When the gate ...

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 ...

This is the third installment in our CPU design series. In Part 1, we covered computer architecture and how a processor works at a high level. Part 2 explored the design and implementation of ...

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 ...
