We describe the properties of the detector as a power amplifier theoretically. In our first experiments power gain of 23 was reached in a good agreement with the theory. The gain facilitates noise matching of the readout circuit to the detectors in the case of time division multiplexing.4 pages, 3 figuresSuperconductivityInstrumentation and Detectorstext
