Design of Pixel-Level ADCs for Energy-Sensitive Hybrid Pixel Detectors

Spectroscopic Quantum Imaging Using Pixel-level Adcs in Semiconductor-based Hybrid Pixel Detectors

Towards a single-photon energy-sensitive pixel readout chip: pixel level ADCs and digital readout circuitry

Unlike conventional CMOS imaging, a single photon imager detects each individual photon impinging on a detector, accumulating the number of photons during a certain time window and not the charge generated by the all the photons hitting the detector during said time window. The latest developments in the semiconductor industry are allowing faster and more complex chips to be designed and manufa...

Design of analog-to-digital converters for energy-sensitive hybrid pixel detectors

An important feature of hybrid semiconductor pixel detectors is the fact that detector and readout electronics are manufactured separately, allowing the use of industrial state-of-the-art CMOS processes to manufacture the readout electronics. As the feature size of these processes decreases, faster and more complex electronics can be designed and manufactured. Furthermore, most new CMOS process...

Pixel-Level Analog-To-Digital Converters for Hybrid Pixel Detectors with energy sensitivity

Single-photon counting hybrid pixel detectors have shown to be a valid alternative to other types of X-ray imaging devices due to their high sensitivity, low noise, linear behavior and wide dynamic range. One important advantage of these devices is the fact that detector and readout electronics are manufactured separately. This allows the use of industrial state-of-the-art CMOS processes to mak...

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...
