This paper introduces a design independent extension to RTL-to-GDS design-flows for seamless insertion of timing-detection flip-flops at critical paths of a digital CMOS standard-cell circuit. It is possible to detect timing-errors for general purposes at any critical path including enable-inputs of clock-gating cells with typically 15% area overhead for 20% endpoint coverage while maintaining DFT...
The level of requirements for a readout front-end electronics dedicated for X-ray imaging applications, such as: high count rate ability of input pulses, low noise, low power dissipation and low silicon area occupation noise, is still increasing. The question: what one can do to minimize silicon area and keep front-end electronics analog parameters at a desirable level at the same time, is still important...
This paper presents the circuits and systems developed for testing the DSToTIC3 ASIC. Detailed study of the estimated noise performance in the presence of realistic external components is also a subject of this paper. DSToTIC3 is a prototype, 8-channel front-end electronics designed for the regime of long silicon strip sensors and interconnects of new tracking detectors. Layout and general architecture...
This paper deals with design of readout system, and then its monolithic implementation, intended for spectroscopy in THz range. At the beginning, the fundamentals of THz spectroscopy based on selective NMOS pixel line, and its possible applications for materials identification are presented. Next, the preceding work on single-channel readout circuit is shortly recalled, with a special emphasis on...
Electro-thermal models are commonly used in simulations and designing MEMS devices, also in case of microbolometers. These models allow to estimate sensors performance before fabrication that consequently impacts on fabrication cost. Coupling of electric and thermal domains and building appropriate model for carrying out simulations are crucial to detect all phenomena having impact for Readout Integrated...
This paper presents multi-objective optimization of a front-end electronics implemented in multichannel integrated circuit for silicon sensors readout in the Silicon Tracking System in the CBM experiment at the FAIR center. We present the optimization towards low-power (< 8 mW/channel) and low-noise while keeping the channel pitch of 58 μm and minimum number of external components required for...
This paper analyzes some advantages of Silicon-on-Insulator (SOI) based photodetectors for bioluminescence imaging. It shows that SOI based sensors not only solve the bulk carriers problem, it can also act as a very selective spectral filter by acting as a resonant cavity, which is useful in application with a very narrow spectrum of interest, such as bioluminescence imaging. Then, the authors discuss...
This paper introduces some design and measurement techniques that were used in the design and the testing of an ASIC for ultra-low current sensing. The idea behind this paper is to present the limitations in sub-picoampere current measurements and demonstrate an ASIC that can accurately measure the different sources of leakage currents and the methodology of measuring. Then the leakage current can...
The paper presents a highly efficient system for automated wafer testing implemented on a single software platform. Building fully functional device requires often expensive and time consuming, manufacturing steps. Thus, the ASICs on the wafer ought to be tested in advance to ensure that only the chips with no manufacturing defects will be used in the further process. The presented testing system...
