    "abstract": "Scaling of multi-pixel cryogenic detectors for imaging becomes increasingly\ndifficult with size due to complexity of readout circuitry and cryogenic\nconstraints (thermal load from wiring). We propose and demonstrate a new\nreadout scheme based on a highly stable RF oscillator composed of a\nsuperconducting tunnel junction which exhibits relaxation oscillations. The\noscillation frequency is almost linear with the analog bias signal over a wide\noperation range. The frequency signals from different detectors can be combined\ninto one single readout line. The current noise of an optimized circuit is\nabout 5 pA/sqrt(Hz), which is comparable to standard SQUID amplifiers. We show\nexperimental data from `stand-alone\u0027 operation as well as response to\nmicrocalorimeter X-ray signals.",
