Development of Low-Noise Charge-Sensitive Preamplifier Based on PIPS Detector

A Low-Noise, Wideband CMOS Charge Sensitive Preamplifier for the High Precision Pixel Detector

A 0.18μm CMOS low-noise wideband charge sensitive preamplifier (CSP) used in a high precision pixel detector was presented in this paper. The preamplifier consists of charge amplification and constant current feedback circuit to accumulate the input charge signal in the feedback capacitor and discharge it by constant current. The open-loop gain of the preamplifier is 52dB at DC, and -3dB bandwi...

Noise Analysis of Radiation Detector Charge Sensitive Amplifier Architectures

In this work, a detailed comparison of four equivalent charge-sensitive, folded-cascode amplifiers in terms of noise performance is presented. A couple of complementary structures, one with a noise-optimised input nMOSFET and the other with a noise-optimised input pMOSFET were designed in 0.35 μm CMOS process by Austria MicroSystems (AMS). Another couple of complementary structures consisting o...

DEVELOPMENT OF A LOW NOISE PREAMPLIFIER FOR THE DETECTION J&ND POSITION DETERMINATION OF SINGLE ELECTRONS IN A ~ERENKOV RING IMAGING DETECTOR BY CHARGE DrvIsIoN*

A preamplifier having 500 electrons noise (rms) has been developed for the detection and location of single electrons in a CRID detector at the SLD. A single channel contains preamp, RC-CR shaper, gain adjustment, driver, and calibration circuitry. Noise and linearity measurements are presented.

The Design Aspects for Ultra Low-Power, Low-Noise 90 nm CMOS Charge Sensitive Amplifier for the Active Pixel Detector

A falling particle in the digital registration systems for elementary particles active pixel detector induces electric charge, the value of which describes the parameters of the particle in the detector. Since the electric charge induced by a single particle is relatively weak, the detector signal is first processed (amplified and shaped) right in the zone of irradiation and only then transmitt...
