Abstract
The invention relates to a method and apparatus for processing the output signal of a low-noise sensor, particularly a squid. According to the invention, the output signal is coupled back to the sensor input by means of a resistance is set to be suitable by adjusting the rate of the resistor from room temperature, for instance by means of voltage.
