A Charge Sensitive Amplifier for time and energy measurements
2008 IEEE Nuclear Science Symposium Conference Record, 2008Silicon detectors are applied to measure precisely the energy loss of penetrating particles. The classical front end electronics for accurate energy measurements is a Charge-Sensitive-Amplifier (CSA). Modern data acquisition systems, which use time stamps to synchronize events, require in addition good timing properties of the sensors. In this paper we

Calibration methods of charge sensitive amplifiers at the Colorado dust accelerator
Review of Scientific Instruments, 2020Charge sensitive amplifiers (CSAs) are electronic integrating circuits frequently used for detecting quick charge pulses such as those produced in semiconductor detector devices and electron multipliers. One of the limitations of highly sensitive CSA circuits is the accuracy with which they can be calibrated due to the necessity of using injection ...

A Correlated Double Sampling Technique for Charge-Sensitive Amplifiers based on TFTs
2022 IEEE International Symposium on Circuits and Systems (ISCAS), 2022In this work is presented a low-noise Charge Sensitive Amplifier (CSA) suitable for the readout of high-impedance pyroelectric sensors. The circuit exploits a novel Correlated Double Sampling (CDS) technique which allows both continuous-time integration and cancellation of the Thin-Film Transistor (TFT) 1/f noise.

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.

Statistical Analysis of the Saturation of Charge Sensitive Pre-Amplifiers
IEEE Transactions on Nuclear Science, 2007The problem of the charge sensitive preamplifier (CSPA) saturation is considered. It is shown that statistical uncertainty of the CSPA saturation time intervals is small in real measurements and it is possible to apply a periodical programmable external reset of CSPA (as well as programmable protection of other electronic blocks in a spectrometer ...
