Oscilloscope persistence displays
Persistence displays retain waveform traces on the screen, allowing them to decay over a user set time duration, they allow users to see a history of signal variations on the screen. This feature is very useful if you are adjusting a signal,…
Will AI PCs be a new sweet spot for CPUs and DRAMs?
The personal computer (PC) industry is warming up to a new sweet spot: PCs incorporating artificial intelligence (AI) capabilities. Intel and Microsoft—the primary beneficiaries of the PC revolution—are now pushing PCs with AI-enabled CPUs…
Reference design serves Lunar Lake CPU
Cirrus Logic, Intel, and Microsoft are developing a reference design that teams Intel’s forthcoming Lunar Lake processor with Cirrus audio and power devices. The reference platform will help developers create more immersive audio for laptop…
16-bit audio ADC detects breaking glass
Asahi Kasei’s AK5707 ADC packs an acoustic activity analyzer (AAA) that can be configured to detect specific types of acoustic events, such as breaking glass. This integrated analog acoustic event detector makes the AK5707 16-bit monaural…
LTE-M module integrates GNSS receiver
Sara-R520M19, an LTE-M and NB-IoT module from Swiss provider u-blox, delivers accurate positioning data concurrent with LTE communication. Simultaneous GNSS and cellular connectivity is an important factor for applications requiring continuous…
PAM4 DSP toolkit optimizes cable design
MaxLinear is offering a product design kit (PDK) to help cable manufacturers integrate the Keystone PAM4 DSP into their active electrical cables. According to MaxLinear, the 5-nm PAM4 DSP can yield up to a 40% power savings over competitor solutions…
Current sensors cover DC to 5 MHz
Two wideband current sensors from Allegro, the ACS37030 and ACS37032, ensure efficiency and reliability in GaN and SiC FET power architectures. With an operating bandwidth of DC to 5 MHz, the devices are suitable for electrified vehicles, clean…
Parsing PWM (DAC) performance: Part 2—Rail-to-rail outputs
Editor’s Note: This a four-part series of DIs proposing improvements in the performance of a “traditional” PWM—one whose output is a duty cycle-variable rectangular pulse which requires filtering by a low-pass analog filter to produce…
Neon lamp blunder
There was this test system that comprised a huge row of equipment racks into which various items of test equipment would be mounted. Those items were a digital multimeter, an oscilloscope, several signal generators and so forth. Each section…
∆Vbe differential thermometer needs no calibration
Differential temperature measurement is a handy way to quantify the performance of heatsinks, thermoelectric coolers (TECs), and thermal control in electronic assemblies. Figure 1 illustrates an inexpensive design for a high-resolution differential…
Faraday to manufacture 64-bit Arm processor on Intel 1.8-nm node
The paths of RISC processor powerhouse Arm and x86 giant Intel have finally converged after they signed a collaboration pact to manufacture chips on Intel’s 1.8 nm process node in April 2023. Hsinchu, Taiwan-based contract chip designer Faraday…
Walmart’s Mobile Scan & Go: Who it’s for, I really don’t know
During Amazon’s annual Prime Day (which is two days, to be precise, but I’m being pedantic) sale mid-July last year, Walmart coincidentally (right) ran a half-off promotion for its normally $98/year competing Walmart+ membership service…
