CUBE - The Charge Sensitive Preamplifier for Radiation Detectors
CUBE is a family of single-channel low-noise charge sensitive preamplifiers built in CMOS technology and exclusively tailored for radiation detectors. The circuit is designed to offer the best noise performance at short peaking times enabling low dead time and high-count rate measurements with excellent energy resolution.
