Noise performance of the charge sensitive amplifier for photodetection
2007 IEEE Nuclear Science Symposium Conference Record, 2007An integrated circuit for charge sensitive amplifier (CSA) was developed for X-ray detection. The circuit has been optimized for reading signals from silicon strip detectors with few pF input capacitance for low power and low noise. Theoretical calculations and optimizations are presented and compared with experimental results. Noise as low as 237 ENC [

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

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 procedure for optimizing the power consumption of a charge-sensitive amplifier
Instruments and Experimental Techniques, 2015Problems of optimizing of the power consumption of a CMOS charge-sensitive amplifier for reading out the signals of multichannel silicon and gas detectors with capacitances up to 100 pF are discussed. In multichannel systems, the power consumption of electronics is limited.

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 ...

A hybrid charge sensitive amplifier for high capacitance detectors
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1988Abstract In the framework of the UA1 upgrading program a hybrid amplifier suitable for amplification of high capacitance detector charges has been developed. The adopted scheme, although very classical [V. Radeka, IEEE Trans. Nucl. Sci. NS-21 (1974) 51], will be discussed and performance presented.

Note: A charge sensitive spectroscopy amplifier for position sensitive micro-channel plate detectors
Review of Scientific Instruments, 2014A compact and low noise charge sensitive spectroscopy amplifier which can be integrated into position sensitive micro-channel plate (MCP) detectors has been constructed. The amplifier was optimized by using a wave form generator and tested by a chevron shape MCP detector.

Reset charge sensitive amplifier for NaI(Tl) gamma-ray spectrometer
Applied Radiation and Isotopes, 2015The time constant of the output signal of the front-end readout circuit of a traditional gamma-ray spectrometer with a NaI(Tl)+PMT structure is affected by temperature, measurement environment and the signal transmission cable, so it is difficult to get a good resolution spectrum, especially at higher counting rates.

A Verilog-A model of a charge sensitive amplifier for a HV-CMOS pixel sensor
2016 13th International Conference on Synthesis, Modeling, Analysis and Simulation Methods and Applications to Circuit Design (SMACD), 2016The use of hybrid pixel detectors in High Energy Physics (HEP) have allowed particle tracking reconstruction with an unprecedented precision. These detectors are expensive to assembly and the bump size limits the minimum pixel size. In order to overcome those limitations full monolithic pixels are being investigated.
