The sensor in question produces a relatively tiny voltage of -0.414 to +0.414 volts, and requires a very high input impedance. A FET input op-amp is selected, with the ground of the sensor shifted ...

Researchers have developed a novel brain sensor that picks up on users' brain signals with impressive accuracy—and it's so small that it ... increase the signal quality by getting closer to ...

The tiny signal amplifier is aimed at making future radar-observing and telecommunications space missions feasible. Developed ...
