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. The CUBEs are available in different versions matching a wide range of X and Gamma ray detectors.

- Detector capacitance compatibility: from <0.25 pF to 10 pF
- Reset mode: pulsed reset or continuous (with external resistor)
- Rise time without detector: 7ns
- Power consumption: from 6 mW to 60 mW
- Silicon Drift Detectors (SDD)
- Silicon PIN diode (Si-PIN)
- High Purity Germanium (HpGE)
- CZT and CdTE detectors
