Digital pixel readout integrated circuit architectures for LWIR

This paper presents and discusses digital pixel readout integrated circuit architectures for long wavelength infrared (LWIR) in CMOS technology. Presented architectures are designed for scanning and staring arrays type detectors respectively. For scanning arrays, digital time delay integration (TDI) is implemented on 8 pixels with sampling rate up to 3 using CMOS 180nm technology. Input referre...

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...

Detector Arrays for Digital Holographic Storage Applications

This chapter discusses detectors for holographic data storage applications. While it may be possible to use a single detector or linear array of detectors, the focus here is on 2-D arrays of pixels. There are many considerations for the detector array when designing a complete system that arise from the intimate relationship between the holographic storage system, optical readout technique and ...

Experimental Determination of the 3dB Frequency of the Spatially Modulated Light CMOS Detector as a Function of Technology

The Spatially Modulated Light CMOS detector (SML CMOS detector) has taken away the conventional speed limit linked with photodetectors implemented in standard CMOS technology [1-3]. High-speed light detectors can be integrated with the CMOS receiver circuitry on the same silicon wafer without the usage of hybrid technology nor additional process steps. This indicates that the SML-detector will ...
