[align=left][color=#000]I’m sure you’ve experienced the following scenario: Your engineering manager comes to you one morning and says, “We need to add connectivity to product ‘x,’ but we don’t want t...
I would like to ask you seniors, when I use IR2127 to drive high-end NMOS (circuit shown in Figure 1), the input drive signal of IR2127 is shown in Figure 2, and the waveform of the gate is shown in F...
A complete DSP program consists of at least three parts: program code, interrupt vector table, and link command file (or link configuration file) (*.cmd).The link configuration file determines the opt...
[[i]Editor's note: Ulrich Drepper recently asked us if we would be interested in publishing a longer article he wrote on memory. We didn't have to read too much to know that LWN readers would enjoy it...
UHF and HF are both general technology categories, but each category has independent supporting protocols. HF is more consistent in the 13.56MHz frequency band, although there are many internation...[Details]

At the beginning of this century, Veit used Einthoven's galvanometer to record the electrical activity of the human pregnant uterus from the body surface for the first time. In 19...[Details]
Designers of hearing aids have stringent requirements. Hearing aids must be small enough to fit in or behind the ear, operate on ultra-low power, and be free of noise or distortion. To meet these requ...[Details]
As the whole equipment is becoming increasingly miniaturized and power-saving, low-dropout linear regulators (LDOs) with low power consumption are becoming the mainstream in the market for linear regu...[Details]
Signal sources have developed to a very wide range today. We can classify them according to the frequency range: ultra-low frequency (0.1m~1kHz), audio (20Hz~20kHz), video (20kHz~10MHz), radio fre...[Details]
This article first briefly introduces the working principles of current mode and voltage mode and their respective advantages and disadvantages; then discusses the ideal voltage mode using output c...[Details]
Today's mobile phone production testing faces an increasingly complex environment, with challenges of multiple frequency bands and multiple standards, pressure on production test speed, and pres...[Details]
With the continuous emergence of new technologies and the increasing complexity of DSP real-time systems, there are more and more different types of external devices. Writing drivers for these exte...[Details]
