A fast charge sensitive amplifier
Nuclear Instruments and Methods, 1978Abstract Amplifier input circuitry response to a sequence of Gaussian pulses of charge is investigated in detail. A solution of the differential equation for the charge Q valid for all time, and approximate solutions valid in the long time limit, are presented and discussed.

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.

Ultra-Low Noise Charge Sensitive Amplifier for MEMS Gyroscope
2009 Fifth International Conference on MEMS NANO, and Smart Systems, 2009This paper describes a ultra-low noise charge sensitive amplifier for readout of micromechanical capacitive sensors. This CSA employs a band-pass amplifier with n-JFET mu-amp achieving high gain and a very low power. The noise due to resister establishing a stable dc bias at the sensing electrodes is minimized by the capacitance multiplier of the mu ...

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 ...
