In the “Say It with Me” series, we’ll take a commonly used concept out of electronics and explain it the best we can. If there’s something that’s been bugging you, or a certain term or concept that ...

Negative input impedance in power supplies can amplify external line noise, causing deceptive conducted emissions failures.

The input impedance of a.c.-coupled op amp circuits depends almost entirely on the resistance that sets the d.c. operating point. If CMOS op amps are used, the input is high, in current op amps up to ...

When considering any new part in the signal chain, input/output impedance is usually an important spec to “bolt” the necessary signal-chain blocks together properly. For a high-speed converter, this ...

In the “Say It with Me” series, we’ll take a commonly used concept out of electronics and explain it the best we can. If there’s something that’s been bugging you, or a certain term or concept that ...

There came a time when high-speed electronic circuits reached speeds that required engineers to analyze the design for signal ...

A young teacher went to Temple. Several priests and pharisees asked him questions. They asked trick questions to try to fool him. The teacher very sweetly and ...

I was wandering through the nearby Bestbuy/Unnecessary-Service-Plans-R-Us with my friend this weekend, killing Saturday boredom with mindless browsing. While we were examining some very nice computer ...

Many industrial and medical applications use instrumentation amplifiers (INA) to condition small signals in the presence of large common-mode voltages and DC potentials. The three op amp INA ...

As you probably know if you've been shopping for cables, coax for most video applications is "75 ohm" coax–but what the heck does that mean, anyway? This article is a short, non-technical explanation ...
