A “cheap as chips” open-source Analog Computer can run circles around a Raspberry Pi in solving differential equations and for simulating natural phenomena. To keep costs down, the Anabrid team ...

In the first of three parts, Andy hypothesizes that the K2-W Analog Computer Op Amp’s design has some unrevealed mad science in its input-stage design. 1. K2-W Op Amp schematic from Bob Pease’s ...

Physicists have invented a new type of analog quantum computer that can tackle hard physics problems that the most powerful digital supercomputers cannot solve. New research published in Nature ...

Where digital and analog designs are overlapping, and why it’s becoming more difficult to ensure they work as expected over their lifetimes. Pujol: We need some abstraction because we cannot ...

For decades, electronics has been taught in a "bottom-up" fashion, with students spending years on calculus, physics, linear algebra, differential equations, circuit theory, and device modeling before ...

While digital computers have become entrenched in our daily lives, a new analog quantum computer offers a stark contrast in both its design and capabilities. A team of physicists from Stanford ...

Ultra-low-voltage CMOS analog circuits operate from supply rails below 0.5 V to minimise power consumption in portable and energy-harvesting systems. Achieving high open-loop gain, flat frequency ...

Analog-to-digital converters (ADCs) transcribe continuous signals into digital form, underpinning applications from telecommunications and biomedical imaging to instrumentation. Key ADC architectures ...
