Introduction The first papers that proposed on-chip mixed-signal built-in self-test (MS-BIST) were published about ten years ago [1]. The first commercial products were announced five years ago at ITC’97 – LogicVision’s adcBIST [2] and pllBIST [3]. The latter tests more PLL parameters than most companies do, and everything is done on-chip in 4K gates: stimulus, response analysis, and comparison...
In this paper, an efficient methodology to retargeting and reuse of embedded mixed-signal blocks is presented. Parametrized layout templates, accurate behavioral modeling of mixed-signal blocks, and appropriate mechanisms for tuning sized circuits to new sets of specs are its key components.
During the past decades, we have witnessed a progressive substitution of analog-based solutions by digital ones, in parallel with the continuous evolution of technological processes, especially CMOS, towards deep submicron technologies. This technological shrinkage has enabled the integration of more and more functionalities on a single chip, with the consequent reduction in area, cost and powe...
Substrate noise generated by digital circuits on mixed-signal ICs can disturb the sensitiveanalog/RF circuits, such as Low Noise Amplifier (LNA), sharing the same substrate. This paperinvestigates the adverse impact of the substrate noise on a high frequency cascode LNA laid out on alightly doped substrate. By studying the major noise coupling mechanisms, a new and efficientmodeling method is p...
We propose an antipiracy security approach for programmable analog and mixed-signal (AMS) integrated circuits (ICs). The relies on functionality locking by leveraging the inherent programmability utilizing configuration settings as secret keys or, equivalently, programming bits key bits. When invalid are applied, circuit is untuned and, a result, its breaks, i.e., at least one of performances v...
Continuous advances in IC (integrated circuits) processing technologies offer the possibility to produce integrated circuits with increased complexity and capability at a reduced cost. In addition, integrated circuits are composed more and more of heterogeneous embedded systems with various kinds of digital, analogue, and mixed-signal circuits and sensors that are integrated on the same IC. In ...
This paper provides a detailed description of the IBM SiGe BiCMOS and rf CMOS technologies. The technologies provide high-performance SiGe heterojunction bipolar transistors (HBTs) combined with advanced CMOS technology and a variety of passive devices critical for realizing an integrated mixed-signal system-on-a-chip (SoC). The paper reviews the process development and integration methodology,...
The wireless communication systems design plays the important roles in the field of microelectronics and system-on-chip methodologies. Traditional digital, mixed signal and analog low-frequency designers have enjoyed an integrated front-to-back IC design system. On the other hand, radio frequency or microwave designers with a discrete design background have used board-level computer-aided desig...
Concerning the fact that the design of contemporary integrated circuits (IC) is practically impossible without using sophisticated Electronic Design Automation (EDA) software, this paper gives some interesting thoughts and considerations about that issue. As technology processes advances on year basis consequently EDA industry is forced to follow this trend as well. This, on the other hand, req...
AbStRACt As the industry migrates to more advanced manufacturing technologies, growing complexity in custom integrated circuit (iC) design threatens to increase delays and dramatically boost the cost of differentiated custom silicon. for semiconductor companies, achieving success in the face of these emerging technical and market challenges rests squarely on their ability to improve the efficie...
