Performance of Silicon Surface Barrier Detectors with Charge Sensitive Amplifiers
IRE Transactions on Nuclear Science, 1961Silicon surface barrier diode detectors of 1 cm2 and 25 mm2 sensitive area have given pulse height spectral resolutions of 17 kev and 13-? kev (FWHM) respectively, for 5.5 mev alpha particles. Reverse currents at 500 volts bias were less than 1 × 10-6 amps/cm2 with breakdown in excess of 1000 volts. A charge sensitive amplifier contributes 3-?

Radiation detector readout circuit with two-stage charge sensitive amplifier
2012 IEEE 11th International Conference on Solid-State and Integrated Circuit Technology, 2012A two-stage charge sensitive amplifier structure suitable for silicon radiation detector with large capacitance is proposed. It has the advantage that the integration capacitor can be large to reduce the gain sensibility to detector capacitance variation without any stability problem. The feasibility of the proposed circuit is verified by comparing the

A low-noise charge sensitive amplifier for MEMS capacitive sensors
2006 8th International Conference on Solid-State and Integrated Circuit Technology Proceedings, 2006This paper describes a low-noise charge sensitive amplifier (CSA) for MEMS capacitive sensors which uses a chopper technique to reduce the low-frequency noise and offset. The feedback resistors of the CSA are implemented as a MOS-bipolar pseudo-resistors and an input common-feedback (ICMFB) is designed to prevent large output errors from input common ...

A Fully Differential Charge-Sensitive Amplifier for Dust-Particle Detectors
2018 14th Conference on Ph.D. Research in Microelectronics and Electronics (PRIME), 2018This paper presents the design and measurements of a fully differential charge sensitive amplifier operating in the frequency range from 7 Hz to 300 kHz. In comparison to the typically employed single input transistor topology, the shown differential approach greatly simplifies the suppression of common mode noise.

Low-noise fast charge sensitive amplifier with dynamic signal compression
2015 IEEE Nuclear Science Symposium and Medical Imaging Conference (NSS/MIC), 2015This work is concerned with the experimental characterization of a Charge Sensitive Amplifier featuring dynamic signal compression, fast recovery time, low noise and reduced area occupancy. The device takes advantage of the non-linear features of an inversion-mode MOS capacitor to fit a wide input dynamic range into the available output swing.
