“…Since a bump-bonded SLS pixel chip (Bro È nnimann et al, 2000) is not yet available, the MPEC chip (Fischer et al, 1998) was used for the present measurements. It is well characterized (Fischer et al, 1999) and provides the same functionality as the SLS chip, except for radiation hardness and pixel geometry.…”

“…The minimum applicable threshold is ∼2000 e − . A 15-bit pseudo-random counter or Linear Feedback Shift Register LFSR [7] is used in a similar manner to the MPEC chip [8]. This counter is incremented each time the discriminator exceeds threshold and provided the shutter is open.…”

Hybrid pixel detectors were developed to meet the requirements for tracking in the inner layers at the LHC experiments. With low input capacitance per channel (10-100 fF) it is relatively straightforward to design pulse processing readout electronics with input referred noise of ∼100 e-rms and pulse shaping times consistent with tagging of events to a single LHC bunch crossing providing clean 'images' of the ionising tracks generated. In the Medipix Collaborations the same concept has been adapted to provide practically noise hit free imaging in a wide range of applications. This paper reports on the development of three generations of readout ASICs. Two distinctive streams of development can be identified: the Medipix ASICs which integrate data from multiple hits on a pixel and provide the images in the form of frames and the Timepix ASICs who aim to send as much information about individual interactions as possible off-chip for further processing. One outstanding circumstance in the use of these devices has been their numerous successful applications, thanks to a large and active community of developers and users. That process has even permitted new developments for detectors for High Energy Physics. This paper reviews the ASICs themselves and details some of the many applications.

“…5, only counter 3 would be increased. The counters are implemented as so called linear feedback shift registers (LFSR) [26] which have several important advantages over a normal binary counter. The difference between a normal binary counter and an LFSR based counter is shown in figure 10.…”

Abstract-We describe a high-rate energy-resolving photoncounting ASIC aimed for spectral computed tomography. The chip has 160 channels and 8 energy bins per channel. It demonstrates a noise level of ENC=214 electrons at 5pF input load at a power consumption of <5mW/channel. Maximum count rate is 17Mcps at a peak time of 40ns, made possible through a new filter reset scheme, and maximum read-out frame rate is 37kframe/s.
