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 ...

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 ...

You have designed an op-amp circuit to measure a small voltage. The circuit gain is -10V/V, but it appears that the input impedance to the circuit is effecting the device as it is being measured. How ...

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 ...

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 ...

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 ...

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 ...
