Until about a decade ago, thermal energy was considered almost entirely as an analog, bulk phenomena. Regardless of whether the heat flux was conducted or radiated, the flux was related to the temperature difference between a hot object and a colder environment. Convective heat transfer was simply a physical result that many things become less dense ...

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 ...
