Rise of the $50 Smartphone: Impact on Analog Articles 6/5/2013 48 comments In the huge markets of China, India, and Southeast Asia, very inexpensive smartphones are being sold by the millions at a price point that is putting downward pressure on analog components in general.
Toshiba begins GaN-on-Si LED production Articles 12/19/2012 3 comments Toshiba has announced that this month it will start production of white light emitting diodes intended for use by makers of general purpose and industrial lighting using Bridgelux technology.
ADC Guide, Part 11: ADC Noise – 2, SINAD, ENoB Articles 12/13/2012 Post a comment Previously in this series, we discussed about noise basics and how they affect an ADC’s output. We will continue this discussion about noise and cover Signal-to-Noise and Distortion ratio and ENoB, all commonly used specifications of an ADC.
ADI introduces two waveform generators Articles 12/11/2012 Post a comment Analog Devices, Inc. has introduced the AD9106 quad-channel, 12-bit, and the AD9102 single-channel, 14-bit, 180-MSPS waveform generators, integrating on-chip static random access memory and direct digital synthesis for complex waveform generation.
ADC Guide Part 10: ADC Noise - 1 Articles 12/8/2012 3 comments To meet system requirements, engineers need to understand the noise performance of all the analog peripherals in the signal chain, including the ADC. In this part of the article series, we will talk about the effect of noise on an ADC’s output.
As an engineer, eventually you will have to insert an equation into your written work or presentation. This can be a struggle as equation editors are not always the friendliest. However, there is good news. The equation editor in Word has improved immensely (I am using version 2010 here). In this blog we look at how to insert an equation into a Word document. As a bonus, there is information on how to insert an equation into a web page with an html code generator website.
Wait a minute. Let’s see if I understand this. (Here I’m channeling you, the puzzled reader, after you’ve grabbed me in the coffee break of a Filter Wizard lecture morning). The frequency of the nth harmonic of a sinusoid is n times that of the fundamental. The nth harmonic distortion is defined as the ratio of the amplitude of the nth harmonic to the amplitude of the fundamental. So the 1st harmonic distortion is… the ratio of the amplitude of the fundamental to the amplitude of the fundamental and that’s… unity. I. Do. Not. Understand.
Single-ended signals are very common, but increasingly signal paths are being converted to differential signals as part of the signal chain. The benefits of differential signaling are particularly appealing with low supply voltage systems and for driving analog-to-digital converters (ADCs).
If you spend any time at all looking at alternative energy sources such as wind power and solar energy, you'll quickly discover one inconvenient truth: alternative energy production is both highly unpredictable and uncorrelated to energy demand.
