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.
Main characteristics
- Availability: bare die or on custom assembly
- Physical size: 0.75 mm x 0.75 mm x 0.25 mm
- Detector capacitance compatibility: from <0.25 pF to 10 pF
- Reset mode: pulsed reset or continuous (with external resistor)
Applications
- Silicon Drift Detectors (SDD)
- Silicon PIN diode (Si-PIN)
- High Purity Germanium (HpGE), CZT and CdTE detectors
