— We report on the design and characterization of a 32 x 32 time-to-digital converter (TDC) array implemented in a 130 nm imaging CMOS technology. The 10-bit TDCs exhibit a timing resolution of 119 ps with a timing uniformity across the entire array of less than 2 LSBs. The differential-and integral non-linearity (DNL and INL) were measured at ± 0.4 and(More)
Imaging techniques based on time-correlated single photon counting (TCSPC), such as fluorescence lifetime imaging microscopy (FLIM), rely on fast single-photon detectors as well as timing electronics in the form of time-to-digital or time-to-analog converters. Conventional systems rely on stand-alone or small arrays (up to 32) of detectors and external(More)

Screen printing allows for direct conversion of thermoelectric nanocrystals into flexible energy harvesters and coolers. However, obtaining flexible thermoelectric materials with high figure of merit ZT through printing is an exacting challenge due to the difficulties to synthesize high-performance thermoelectric inks and the poor density and electrical(More)
— With the emergence of large arrays of high-functionality pixels, it has become critical to characterize the performance non-uniformity of such arrays. In this paper we characterize a 160x128 array of complex pixels, each with a single-photon avalanche diode (SPAD) and a time-to-digital converter (TDC). A study of the array's non-uniformities in terms of(More)
The innermost layer (b-physics layer) of the ATLAS Pixel Detector will consist of modules based on MCM-D technology. Such a module consists of a sensor tile with an active area of 16.4 mm x 60.4 mm, 16 read out ICs, each serving 24 x 160 pixel unit cells, a module controller chip (MCC), an optical transceiver and the local signal interconnection and power(More)
