چکیده

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 of a noise-optimised input npn with a pMOSFET cascode, and the respective structure having a pMOS as input device, were developed in a 0.35 μm SiGe BiCMOS process (AMS). The structures' comparison is performed through simulation, after careful selection of the parameters that remain constant in all four variations.

Leakage Current Compensation for the 0.13 μm CMOS Charge Sensitive Preamplifier

The active hybrid pixel detector (APD) can be a valuable solution in front-end electronics for radiation sensors. Detection systems with high sensor pixilation can benefit from low power, low parasitic, high front-end channel density, and low cost per channel. In addition, the APDs are characterized by good radiation tolerance [1-3] and can integrate large amount of additional signal processing...

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...

A Position-Sensitive Ionization Chamber for Thermal Neutrons

A position-sensitive neutron detector based on He is being developed for a national crystal backscattering spectrometer (CBS) at a pulsed neutron source. It comprises a single gas volume, of constant depth, in the form of an annulus that is also part of a truncated cone. Charge from each event is collected on one or two anode strips, out of a total 336 around the annulus, yielding an angular re...
