Lenovo’s Smart Clock 2 Charging Dock: Multiple lights and magnetic “locks”
Two months ago, EDN published my teardown of Lenovo’s Smart Clock 2:
I’d mentioned in it that my dissection victim, acquired at steep discount from the original MSRP, included the “optional charging dock for both it, a wireless-charging…
APEC 2024, Day 1: Daily Briefing Video
Welcome to the first day of the 2024 APEC conference, where global leaders converge to discuss pivotal topics shaping our technological landscape. Today, we delve into the field of semiconductor technology, exploring the transformative potential…
Voltage inverter uses gate’s output pins as inputs and its ground pin as output
When analog circuits mix with digital, the former are sometimes dissatisfied with the latter’s usual single supply rail. This creates a need for additional, often negative polarity, voltage sources that are commonly provided by capacitive…
Computer upgrades: Motivations, hiccups, outcomes, and learnings
I habitually, admittedly, hold onto computers far longer than I should, in the spirit of “if it ain’t broke, don’t fix it” (not to mention “a penny saved is a penny earned”). What I repeatedly forget, in the midst of this ongoing…
An MCU test chip embeds 10.8 Mbit STT-MRAM memory
A prototype MCU test chip with a 10.8 Mbit magnetoresistive random-access memory (MRAM) memory cell array—fabricated on a 22-nm embedded MRAM process—claims to accomplish a random read access frequency of over 200 MHz and a write throughput…
MRAM macro speeds read/write operations
Renesas presented an embedded MRAM macro in an MCU test chip at ISSCC 2024 that delivers a random-read access frequency of over 200 MHz. The test chip also exhibited a write throughput of 10.4-Mbytes/s.
The company developed two high-speed…
SP4T switches offer high isolation up to 8.5 GHz
pSemi announced production readiness of two UltraCMOS SP4T RF switches that operate from 10 MHz to 8.5 GHz with high channel isolation. According to the manufacturer, the PE42445 and PE42446 switches integrate seamlessly into 4G and 5G base…
Development kit pairs RISC-V and FPGA
The PolarFire SoC Discovery Kit from Microchip makes RISC-V and FPGA design accessible to a wider range of embedded engineers. This low-cost development platform allows students, beginners, and seasoned engineers alike to leverage RISC-V and…
100-V MLCC is among the industry’s smallest
Murata expands its GJM022 series of high-Q multilayer ceramic capacitors (MLCCs) with a 100-V device that is just 0.4×0.2 mm (L×W). The MLCC is intended for high-frequency module applications, such as those used in cellular communication infrastructure.
Exhibiting…
BLDC motor driver prolongs battery life
A three-phase BLDC motor driver, the AOZ32063MQV from AOS, offers an input voltage range of 5 V to 60 V and 100% duty cycle operation. The IC enables efficient motor operation, while its low standby power helps extend the battery life of cordless…
Logic Probe has a wide voltage range
The logic probe is powered from the device under test (DUT)—it may be any binary logic, which can be powered in the range +2 V to +6 V. This may be a microcontroller or 74/54 series logic chips, including HC/HCT chips.
Wow the engineering…
Making waves: Engineering a spectrum revolution for 6G
6G is looking to achieve a broad range of goals in turn, requiring an extensive array of technologies. Like 5G, no single technology will define 6G. The groundwork laid out in the previous generation will serve as a starting point for the new…
