This ultra-low noise amplifier and simple power supply was found in Analog Devices documentation from the 90's. The circuit can be implemented with modern equivalent components.
The presence of a low resistance between the terminals of the sensor causes this modulated...
This circuit was found in a 1970 IEEE publication. The circuit functions as a voltage controlled...
I found this circuit in a 1992 Electronics Experimenter Handbook. The circuit can be easily...
