Prospects for charge sensitive amplifiers in scaled CMOS

1999 IEEE Nuclear Science Symposium. Conference Record. 1999 Nuclear Science Symposium and Medical Imaging Conference (Cat. No.99CH37019), 2003
Due 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 50 fF to several hundred pF, and applications call for pulse ...

A Charge Sensitive Amplifier for time and energy measurements

2008 IEEE Nuclear Science Symposium Conference Record, 2008
Silicon 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

The phenomenology of low noise charge sensitive amplifiers

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1985
Abstract 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.

A Correlated Double Sampling Technique for Charge-Sensitive Amplifiers based on TFTs

2022 IEEE International Symposium on Circuits and Systems (ISCAS), 2022
In 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.

Noise performance of the charge sensitive amplifier for photodetection

2007 IEEE Nuclear Science Symposium Conference Record, 2007
An 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 procedure for optimizing the power consumption of a charge-sensitive amplifier

Instruments and Experimental Techniques, 2015
Problems 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, 2007
The 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, 1988
Abstract 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, 2014
A 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.
