Prospects for charge sensitive amplifiers in scaled CMOS
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2002Due to its low cost and flexibility for custom design, monolithic CMOS technology is being increasingly employed in charge preamplifiers across a broad range of applications, including both scientific research and commercial products. The associated detectors have capacitances ranging from a few tens of fF to several hundred pF.

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.

The phenomenology of low noise charge sensitive amplifiers
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1985Abstract The equations describing the noise performance of charge sensitive amplifiers have been reported in several papers. In this article, these equations are evaluated for several practical sets of amplifier parameters under a wide variety of operational conditions.

, 2019 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.
