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 ...

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 ...

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 ...

If the resistor and capacitor values in your circuit are not properly calculated, then the output may be distorted and the amplitude may vary with time. If the resistor and capacitor values in your ...

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 ...
