This article presents a biopotential recording analog front-end (AFE) specifically tailored for a two-electrode measurement system, capable of capturing small biopotential signals while tolerating a large common-mode interference (CMI) over… The post A 4.6 μW, 133-VPP Common-Mode Interference-Tolerant Biopotential Amplifier for Two-Electrode Recording System in 110-nm CMOS appeared first on IEEE Solid-State Circuits Society.| IEEE Solid-State Circuits Society
Sony doesn’t like to talk about their SMC-777 very much, but this unloved middle child represents an entire parallel universe of Japanese 8-bit computing. Today, we’ll take an extremely battered example and get it working again.| Leaded Solder
I have a Multia (VX40) that developed intermittent failure to POST, and had a very hot 3.3V rail. It seems this is because a capacitor on the system gets sheared off the board by a metal locating peg when the… Continue reading →| the sporks space
Ever wondered why 100nF is a go-to value for decoupling capacitors? This number has pervaded in datasheets and electronics advice going back to the 1980s, and is still widely present in the datashe…| codeinsecurity

I’ve been reading about capacitors a lot lately. Not just their high-level circuit behaviours, but also their materials and physical properties. I put together a heap of notes on the topic. K…| codeinsecurity
