- Fabio Cacciotto, STMicroelectronics EDN Modern appliances offer a range of features that rely heavily on microcontrollers and auxiliary circuits. Although conventional iron-core transformers can provide ac line-isolated, low-voltage power for a ...Apr 26, 2017
- Stephen WoodwardA sensitive and reliable way to measure airflow is to take advantage of the predictable relationship between heat dissipation and air speed. The principle of thermal anemometry relies on King's Law, which dictates that the power required to ...Jan 31, 2017
- Carlos Castro-Miguens José Benito Castro-MiguensProtect circuits from high current until a capacitor charges A high-power offline supply is nothing more than a half- or full-bridge dc/dc converter. Rectifying the ac line yields a dc voltage that feeds the converter. At power-supply turn-on, the ...Oct 10, 2016
- Jim McLucasA recent Design Idea described a method for designing simple, high-frequency LC oscillators with few passive components ( Reference 1 ). However, for best results, practical hardware design of a stable oscillator requires more parts and greater ...Jun 1, 2016
- Alex Rysin Electronic Design This idea analyzes the reason that a capacitively coupled load may result in a clipped negative output, and shows the conditions that must be met to avoid this undesired situation. An engineer asked me for help when he ...Dec 22, 2015
- Todor ArsenovMost isolated, offline SMPSs (switched-mode power supplies), including flyback, forward, and resonant, must operate at input voltages of 90 to 260 V rms. Some cases even use line-to-line voltages of 400 V rms 10%, leading to increased ...Sep 1, 2015
- Rick Malley, Independent Designs LLC Electronic Design Using eight digital inputs, this circuit simplifies decoding of the common membrane 4×4 keypad matrix and eliminates the traditional requirement of scanning rows or columns. Any X-Y ...Jul 30, 2015
- Application Note AN4313 November 2013 This application note describes the layout and mechanical design guidelines used for touch sensing applications with projected sensors. This document describes only what is specifically related to projected ...Dec 21, 2013
- Application Note AN4391 November 2013 Delfo Fusillo, Filippo Scrimizzi P-channel and N-channel MOSFETs show a different electrical performance. Due to lower hole mobility (three times smaller than electrons), the magnitude of specific on-resistance ...Dec 21, 2013
- Application Note AN4390 November 2013 The UPS (uninterruptible power supply) is gaining ever increasing importance in office and industrial environments, because it preserves the information and business operations from power supply failure or ...Dec 21, 2013
