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.

A baseline restorer for charge-sensitive amplifiers in a 500-nm CMOS process
2018 IEEE 9th Latin American Symposium on Circuits & Systems (LASCAS), 2018Charge-sensitive amplifiers (CSAs), widely used as front-ends in pulse processors for capacitive detectors, require a feedback network to set the operation point, deal with leakage currents and restore the baseline voltage upon the arrival of signals.

Fully Integrated Charge Sensitive Amplifier for Readout of Micromechanical Capacitive Sensors
2005 IEEE International Symposium on Circuits and Systems, 2005This paper presents a charge sensitive amplifier (CSA) for readout of micromechanical capacitive sensors. The transfer function and noise performance together with noise optimisation are studied from a theoretical point of view. The feedback resistors of the CSA are implemented as long-channel MOS transistors to set the -3 dB corner frequency well ...

Near-Quantum-Limited Operation of a Charge-Sensitive Electrical Amplifier
IEEE Transactions on Nanotechnology, 2010Here, we report the operation of a superconducting single-electron transistor (S-SET) as a fast and nearly quantum-limited charge-sensitive amplifier. By operating the S-SET such that Cooper pair tunneling is resonant across both of its tunnel junctions, we are able to achieve an excellent charge sensitivity of δq = 1.6 × 10-6 e/√(Hz), while also ...

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 ...
