We don't talk enough about the Electrical Engineering and Electrician professions on Planet Analog. My first job out of NYU in 1972 with a Bachelor of Engineering in Electrical Engineering was with a company called Lord Electric. Mr. Juras hired me as an apprentice engineer (I later joined the Local 3 International Brotherhood of Electrical workers-the ...

Sine-wave oscillators such as the Wien-bridge, state-variable, or quadrature oscillators, have an inherently undefined amplitude. Ideally, the poles of their feedback loop are on the jω-axis and the pole-pair defining the resonant frequency has no damping. Yet in real circuits, the amplitude control by the oscillator itself is an unstable equilibrium,

We have frequent input from our customers who are developing supercapacitor modules consisting of two or more cells stacked in series and who want to know how to utilize MOSFETs to balance leakage current. Several engineers had a misconception and dismissed low current MOSFETs because the charge and discharge current of the supercapacitor exceeded that ...

In DAC BASICS, Part 3: Static specifications, we talked about the static specifications and their impact DC characteristics, such as offset, gain, and linearity. These characteristics are generally consistent across the various topologies of the R-2R and string digital-to-analog converters (DACs). In contrast, the glitch-impulse behavior of the R-2R and ...

Just like the quotation in the movie "Apollo 132" and in real life, we design things not to fail. Your "friend" Murphy and Murphy Law 's3 (see Figure 1 below) is out there waiting for you.

With Android continuing to make inroads across the board (64% market share in tablets and 53% in smartphones as of Q1 2015), it's time to take a look at some cool Android apps for analog EEs.
