Electronics Design

Useful filter design tools

Every now and then situation arises where you need to construct simple filter circuits. Usually a low pass circuit is the most often needed one. A low-pass filter is a filter that passes signals with a frequency lower than a certain cutoff frequency and attenuates signals with frequencies higher than the cutoff frequency. Low-pass filters

HAX: the Chinese firm accelerating hardware, not software (Wired UK)

Wired is writing about The Chinese firm accelerating hardware, not software at   http://www.wired.co.uk/magazine/archive/2016/04/features/hax-hardware-accelerator-china In four years, HAX has invested in 100 companies after vetting what general partner Benjamin Joffe says are 1,000 startups a year. “It’s an investment company that functions as a hardware accelerator,” explains Joffe. “We help them manufacture at scale. Then

Chemoelectronics: Nanoparticle Diodes and Devices That Work When Wet – IEEE Spectrum

Whether they’re for sensors in artificial skin that demands flexibility or for wearable electronics where the circuits must withstand our sweat, silicon-based chips aren’t always up to the task. Now, an international research team has developed a way to fabricate flexible, water-loving logic circuits and sensors without the need of semiconductors. Instead, what the researchers have done is coat gold

The Hardware Startup Valley of Death — Bolt Blog — Medium

There’s a valley of death for hardware startups. Ironically, it occurs when companies start selling their product. Pre-revenue startups raise money on stories of limitless potential, of rocketship growth and products flying off the shelves. Post-revenue startups don’t have that luxury. They need to tell stories of revenue growth, high margins, and traction. They need

EUV Lithography’s Prospects Are Brightening – IEEE Spectrum

After a hard slog, extreme ultraviolet (EUV) lithography seems to be closing in on a long-sought quarry: a light source bright enough to pattern chips cheaply and keep Moore’s Law marching along. The technology, which uses 13.5-nanometer light instead of today’s 193-nanometer light, could—at least in the short term—allow chipmakers to create finer features without

Impedance and impedance matching

What is impedance? Impedance is very technical measurement that is hard to explain without equations and some scientific jargon. When you want to understand impedance, first think about electrical resistance (represented by R), measured in Ohms. In basic battery circuit battery generates a voltage which tries to force a current around the circuit connected between

Quantum Computing With Ordinary CMOS Transistors – IEEE Spectrum

Future quantum computers might not be all that different from the one you’re using now. An international team of researchers have created a the most fundamental part of a quantum computer—the quantum bit, or qubit—using only a CMOS transistor that is not much different from those in today’s microprocessors. http://spectrum.ieee.org/nanoclast/computing/hardware/qubits-quantum-computing-with-run-off-the-mill-cmos-transistors Posted from WordPress for Android
