CUBE - The CMOS Preamplifier for Radiation Detectors
CUBE is a low-noise CMOS preamplifier exclusively tailored for radiation detectors. The circuit, a Charge Sensitive Amplifier (CSA) operated in pulsed reset mode, is designed to offer the best noise performance at short peaking times enabling high-count rate measurements with excellent energy resolution.
