New research shows that Apple is looking to improve gestures on AirPods by dropping the separate detection circuitry of ...

A subject rarely found in circuit design textbooks is the matter of nonlinear junction capacitance, especially reverse-bias junction capacitance, also called depletion capacitance. When it is ...

From the micromixer topology by Barrie Gilbert [1], this amplifier allows a single-ended input to be converted to a Class A/B current output from a single supply. Wow the engineering world with your ...

Analytical formulas, plus Microsoft Excel, are all you need. Look at just about any expert-level signal integrity guide and you will (or rather, should) see a lot of simulation data. Most often, these ...

Any PF distortion will alter even a perfectly corrected voltage-current relationship. Modern switch-mode power supplies use a combination of X- and Y-capacitors with inductors to filter common- and ...

Ex-movie theater projectionist Steve Guttenberg has also worked as a high-end audio salesman, and as a record producer. Steve reviewed audio products for CNET and worked as a freelance writer for ...

EMC compliance of a product is annoying but unavoidable. At the same time, EMC filter design is far from trivial. The new REDEXPERT filter designer tool simplifies filter design, helping to save time ...

Abstract: This article models and characterizes the input impedance of a single-phase totem-pole power factor correction (PFC) converter in a virtual synchronous reference (d-q) frame. Due to the dc ...
