Use filter capacitors in linear voltage regulators
System design engineers have to use many capacitors to filter digital noise, expecting to get a clean voltage source as the power supply for analog circuits. This article discusses the effect of filter capacitors. Details... more...
Manage mixed voltages in mem card interfaces
With processors and SDIO peripherals now operating at different interface supply voltages, a level translator has to be added to ensure switching compatibility. System designers now have multiple choices of level translation solutions for controlling the bidirectional flow of data and command signals from processor to card. Details... more...
Measure MEMS gyros for image systems
You may never use a MEMS gyroscope, but you probably have—and will—run across sensors with similar characteristics or systems with similar requirements. This article provides a methodology for designing image systems with reprogrammable mixed-signal microcontrollers. Details... more...
