Much to the chagrin of hardware tinkerers, the Raspberry Pi doesn’t have analog inputs on its GPIO pins. Sure, you can blink a LED with just a few console commands, but reading sensors with a… ...

In this repository we provide cad files and software codes to make and operate an up-to-date instrumentation amplifier (INA) that can accommodate 10Mohm impedances with 16 bit precision at 1MSPS. The ...

Physiological information provided by bio-potential signals is essential and pivotal for biomedical sensors. As the first stage in the signal chain of the sensor, impedance matching of the analog ...
