Texas Instruments (TI) (NASDAQ: TXN) expanded its broad portfolio of industry-leading sensing integrated circuits (ICs) with four new devices that allow engineers to accurately sense key parameters in tight spaces with very low power. These new products provide solutions for temperature, humidity, ambient light and capacitive sensing in a host of industrial and enterprise applications. […]
How to reduce noise in an electrical circuit
“Noise” can mean different things to different people. In general it is associated with something unwanted. It could be acoustic noise – background noise. In electronic terms it will generally be an unwanted electrical signal. That may be random or systematic. Either way, it would be a nuisance if the level is high enough to […]
Low voltage, high performance in Fox’s new 1.8 V XpressO-ULTRA Oscillator
Fox Electronics, a leading global supplier of frequency control solutions and an IDT company, has expanded its XpressO product line to include three sizes of automotive-grade, HCMOS oscillators to meet the advanced clocking requirements in modern vehicle systems. With the same exceptionally low jitter as other XpressO oscillators, the new models conform to AEC-Q200, which […]
2kVAC isolated 1.5W Low noise module converters in 9mm x 11.25mm x 4.92mm BGA package are UL60950 recognized
Open loop gain: how to measure with SPICE
When designing opamps in analog IC design, it is frequently required to plot the open loop gain/phase. One way of doing that is to use a high feedback resistor and very high capacitance so the feedback network has an extremely low corner frequency: This works fine unless your opamp drive capability is low, in which […]
Xilinx and TSMC Reach Volume Production on all 28nm CoWoS™
Xilinx, Inc. (NASDAQ: XLNX) and TSMC (TWSE: 2330, NYSE: TSM) announced production release of the Virtex®-7 HT family, the industry’s first heterogeneous 3D ICs in production. With this milestone, all Xilinx 28nm 3D IC families are now in volume production. These 28nm devices were developed on TSMC’s Chip-on-Wafer-on-Substrate (CoWoS™) 3D IC process that produces significant […]
