It was just a few years ago when the pandemic was reaching its maximum intensity and people in many mainstream and traditional ordinary jobs were being let go for a variety of complicated reasons. There were many stories about people in service jobs, retail, product installation and repair, and basic manufacturing lines being told they were no longer needed. In contrast, software developers—sometimes referred to as “coders” or “programmers” —were in great demand to support the digital-commerce infrastructure, emerging AI applications, the remote-work transition, and more. It seemed that Googl ..read more

Radio wave absorber claims to reduce CO₂ emissions by 13%
Planet Analog
by Majeed Kamran
1w ago
A new radio wave absorber features more than 25 wt% of biomass material—replacing petroleum-derived polyethylene—to enable a reduction of CO₂ emissions by 13% compared to conventional products. TDK’s IS-BP series radio wave absorbers, made of foamed polyethylene with carbon dispersed in it, absorb radio waves by utilizing the ohmic loss of the carbon. The ceiling, walls, and floor of the microwave anechoic chamber are covered with radio wave absorbers, which are used to evaluate antennas, wireless communication equipment, and millimeter-wave radars for autonomous driving and advanced driver a ..read more

Motion detector in Amazon Echo Hub challenges PIR sensors
Planet Analog
by Majeed Kamran
2w ago
A new motion sensor incorporates micromachined thermal transistors to facilitate human presence and motion detection in security systems, home automation equipment, and Internet of Things (IoT) devices that typically use passive infrared (PIR) sensing. Market research firm Yole has found this MEMS-based motion sensor—STHS34PF80 from STMicroelectronics—in a teardown of the Amazon Echo Hub. A sensor that not only detects motion but can also detect presence stands out among other smart sensor products on the market, said Jim Mielke, VP of Consumer Teardowns at Yole Group. “The sensor allows smar ..read more

Prototyping partnership to accelerate Wi-Fi 7 IP verification
Planet Analog
by Majeed Kamran
3w ago
Wi-Fi 7—the latest Wi-Fi technology with speeds of up to 30 Gbps and approximately three times the peak performance of Wi-Fi 6—sets rigorous standards for system-on-chip (SoC) designers and RF IP vendors. That ensures Wi-Fi 7 can efficiently handle 320 MHz bandwidth and 4096-QAM alongside faster, lower-noise ADCs/DACs, sophisticated RF designs, and complex baseband processing. In Wi-Fi 7 RF front-end modules, enhanced error vector magnitude (EVM) and noise control requirements exceed those of Wi-Fi 6/6E. Moreover, features such as multiple resource unit (MRU) and multi-link operation (MLO) in ..read more

Why DACs and ADCs are crucial in scaling up quantum computers
Planet Analog
by Chris Morrison
1M ago
Millions of qubits—rather than the few hundred that are currently possible—are required for quantum computers to achieve their full potential. However, the path toward quantum computer scaling is not only paved by developments in qubit technology. The digital-to-analog converters (DACs) and analog-to-digital converters (ADCs) working in the background also have a critical part to play. So, as quantum computers advance in complexity, these analog components will become increasingly important. DACs are essential in quantum control. These are used to convert digital control signals into analog v ..read more

Dimensional differences complicate simple circuit troubleshooting
Planet Analog
by Majeed Kamran
1M ago
Anyone who has used electrical or electronic products knows that electromechanical components such as cables and connectors are often a source of problems ranging from obvious to intermittent to mysterious. Wiggling, removing, reconnecting, or replacing the cable assembly is a standard technique for finding and overcoming these problems. That’s often frustrating, whether that cable is a relatively simple power cable or a sophisticated gigahertz data cable. Misaligned contacts, bent pins, broken wires, and poor crimping or soldering are all possibilities for several cable issues. Yet other tim ..read more

Automotive-grade chip inductors specialize in noise suppression
Planet Analog
by Majeed Kamran
1M ago
Two new common-mode chip inductors focusing on noise suppression are targeted at advanced driver assistance systems (ADAS), infotainment, body electronics, and other automotive applications. Both common-mode chip inductors are designed with a ferrite core to provide high impedance across a broad frequency range and suppress unwanted incoming or outgoing electromagnetic interference (EMI) signals. As a result, these common-mode chip inductors can address stringent shock and vibration requirements; their core is constructed with 0.3/0.4 mm high sidewall terminals that help enhance the component ..read more

1M ago
A MEMS-based clock-system-on-a-chip (ClkSoC) wants to replace quartz-based traditional clocking devices by overcoming design issues related to noise, electromagnetic interference (EMI), and vibration. SiTime’s new timing solution, Chorus, integrates clock, oscillator, and resonator technologies in a single chip to reduce bill-of-materials (BOM) and simplify system clock architecture. Figure 1 By replacing up to four standalone oscillators, Chorus can reduce the PCB area for timing by up to 50%.

Mixed-signal IP reuse platform eliminates parasitic constraints
Planet Analog
by Majeed Kamran
1M ago
Accurate parasitic estimation is one of the most intricate challenges in mixed-signal semiconductor design. An analog/mixed-signal toolset upgrade claims to eliminate this traditional constraint, streamlining the design process by intelligently incorporating extracted parasitics from the source design and including them in the circuit porting phase to provide estimated parasitics early in the design process. Subsequently, the accuracy of the ported schematic is improved, reducing the need for multiple post-layout parasitic extraction (PEX) iterations by at least 30%. It’s particularly benefic ..read more

1M ago
Three EDA toolmakers have joined hands to facilitate RF design flow migration from TSMC’s N16 process to its N6RF+ technology, which addresses the power, performance, and area (PPA) requirements of today’s most demanding wireless chips. The new migration workflow incorporates RF and millimeter wave (mmWave) solutions from Ansys, Keysight and Synopsys to streamline re-design of passive devices and design components on TSMC’s more advanced RF process. Figure 1 EDA toolset initiative from Ansys, Keysight, and Synopsys aims to facilitate design flow migration from TSMC’s N16 to N6RF+ process tec ..read more
