Circuit Simulation

MY FIRST TIME MACHINE - WELL, AT LEAST MY FIRST FLUX CAPACITOR

With a circuit simulator and a basic knowledge of components and circuit theory, it’s possible to simulate just about any electronic device that can be built. Trouble is that circuit simulators and the underlying models are inherently limiting. However, the great thing about simulation is that you can define your own universe in software. So, go ahead, define that flux capacitor.

Can You Trust Your Voltmeter?

CAN YOU TRUST YOUR VOLTMETER?

Sometimes I wonder which of my portable digital voltmeters I can trust — the B&K, Fluke, or Amprobe. Usually, they’re pretty close but it bugs me not knowing whether they are right on the nose. Fortunately, these days, there are a number of very accurate voltage reference circuits that you can build or purchase for a few dollars.

Understanding Digital Logic ICs

UNDERSTANDING DIGITAL LOGIC ICs - PART 1

Modern digital logic ICs are widely available in three basic types: TTL devices, “slow” CMOS devices, and “fast” CMOS devices. Each of these families has its own particular advantages and disadvantages, and its own special set of usage rules. This mini-series explains the basic principles, usage rules, and provides practical usage guidance for the vast range of ICs available in these families. This first article concentrates on digital logic IC basics.
