Accuracy loss from PWM sub-Vsense regulator programming
I’ve recently published Design Ideas (DIs) showing circuits for linear PWM programming of standard bucking-type regulators in applications requiring an output span that can swing below the regulator’s sense voltage (Vsense or Vs). For example: “Simple PWM interface can program regulators for Vout < Vsense.” Wow the engineering world with your unique design: Design Ideas […]

The Memory Market Isn’t Correcting
Key Things to Know: DRAM pricing no longer follows historical cycles — AI-driven demand doesn’t defer, breaking the supply–demand elasticity that once stabilised the market. Memory makers have shifted from volume to margin — Tight supply is now intentional, with manufacturers prioritising profitability over expansion. HBM is absorbing advanced fab capacity — Each HBM generation […]
Making uncertainty manageable | Latest Articles, North America News
2026 will test resilience but as MPD’ CEO Daniel B Lynch Sr explains, the answer lies in preparation, balancing flexible sourcing, stock and transparent communication. 2026 is shaping up as a year of uncertainty but the real challenge is knowing where it will come from. For Memory Protection Devices, the most significant risks lie in […]
Norton amplifiers: Precision and power, the analog way we remember
The Norton amplifier topology brings back the essence of analog design by using clever circuit techniques to deliver strong performance with minimal components. It is not about a brand name—it’s about a timeless analog philosophy that continues to inspire engineers and hobbyists today. This approach shows why analog circuits remain powerful and relevant, even in […]

Tariffs, cyber threats and AI drive resilience
As ERA’s CEO, Edward Smith explains, amid uncertainty, companies investing early in adaptation and resilience will define the electronics industry’s future in 2026. In 2026 the electronics components industry is facing many uncertain events. Let’s start with tariffs. There are two parts of tariffs: the first part of tariffs is the legality of the US […]
The Fosi Audio V3 Mono: A compelling power amp with a tendency to blow
One of the PFFB (Post-Filter Feedback Technology)-based Class D audio amplifiers showcased in a recent writeup of mine was Fosi Audio’s V3 Mono, which will get sole billing today: It interestingly (at least to me) originally launched as a Kickstarter project in April 2024: As the name implies, it’s a monoblock unit, intended to drive […]

Acoustic Metamaterials Driving Advanced Haptic Systems
Key Things to Know: Acoustic metamaterials use nanoscale resonators to manipulate wave propagation in ways not found in nature, enabling highly localised control of vibrations. Traditional metamaterials often have fixed properties, but active designs—using piezoelectric or electromagnetic actuation—allow real-time tuning. A new dual-state metamaterial built from off-the-shelf linear resonant actuators enables both resonator and actuator […]
