Energy consumption optimization for thermal energy harvester applications

  • Pracoviště: Katedra mikroelektroniky
  • Anotace:
    This paper demonstrates the concept of node consumption reduction for IoT applications. The main emphasis is placed on the autonomy of the whole device, which must be independent of external power supply. That is why energy harvesting based on temperature principle is used for power supply. One of the parameters monitored is the service uptime. The concept of intelligent control of the individual parts of the equipment leads to significant energy savings. This control requires the use of low power components, but only their appropriate connection and mutual monitoring of their operating modes leads to the desired savings. This algorithm can be adapted to the needs of IoT nodes focused on real-time performance applications or the process tracking slow low power applications. This concept will ultimately be adapted to a wireless node for monitoring position and temperature for use in medical applications to monitor the patient's position on the bed or position while moving.

IoT monitoring system for farmers

  • Pracoviště: Katedra mikroelektroniky
  • Anotace:
    This paper discusses the concept, design and testing of a IoT based monitoring system for the needs of farmers. The system consists of integrated autonomous BLE beacons, which are located on the monitored objects (in our model case it is cattle). These beacons transmit their identification data in specified periods together with other additional information, which then serves to perform accurate targeting of the monitored object in the monitored area (meadow, fence). This data is periodically received by a central hub, which brings this information together, eliminates duplications and sends the final datagram containing information about active beacons via the GSM network (or LoRa) to a central server, where the data is subsequently processed. A pilot test experiment is taking place this summer on a private farm in Central Bohemia.

  • Anotace:
    The advent of novel sub-micron technologies of IC fabrication led to such a decrease in lead-to-lead separation that it is not possible any more to neglect the influence of these leads on the reliability of the system operation. Both the small lead separation and the application of multilayer interconnecting systems cause parasitic electromagnetic couplings; in the case of a unipolar CMOS technology, the capacitive coupling is the dominant effect. It is impossible to measure direct the rapid variations voltage between leads inside the IC.

    Spojové soustavy jsou hlavním zdrojem nežádoucích elektromagnetických vazeb ve strukturách integrovaných obvodů. Pro řešení elektromagnetických vazeb je nutné definovat rozložení elektromagnetických polí ve spojové soustavě integrovaného obvodu. Analytické řešení elektromagnetických polí ve spojových soustavách je vhodné pouze pro elementární varianty homogenních vedení. Při řešení reálných variant spojových soustav v integrovaných obvodech je nutné numerické řešení elektromagnetických polí, protože pouze tento přístup umožňuje plně postihnout lokální vlastnosti spojových soustav důležité pro výpočty rozložení elektromagnetických polí.

    Hlavním cílem tohoto článku je řešení elektromagnetické kompatibility ve vnitřních strukturách integrovaných obvodů a mikrosystémů. Elektromagnetická kompatibilita slouží jako míra vzájemné koexistence několika elektronických systémů ve společném prostředí bez nežádoucích elektromagnetických vazeb, které by mohly ovlivnit funkci jednotlivých systémů. Mezi spoji v integrovaném obvodu vznikají nežádoucí elektromagnetické vazby. Při šíření signálů po spojích může dojít prostřednictvím parazitních elektromagnetických vazeb k rušení jiných signálových spojů. Tato rušení pak způsobují vznik nahodilých poruch v integrovaných obvodech.

    The development of integrated circuits has reached a situation today that the circuit operating speed is not limited by the parameters of the transistors any more, but rather by the electrical parameters of the interconnections inside the integrated circuit. For this reason, it is necessary to take in account the properties of interconnecting conductors from the start of the circuit design process. Undesirable parasitic electromagnetic couplings appear between the interconnecting lines, causing the transfer of interfering impulses onto the signal-carrying lines. These interfering impulses then result in random errors and/or disturbances in the integrated circuit.

    The electromagnetic compatibility (EMC) is one of the most important reliability parameters of electronic systems and devices. When EMC effects are properly taken care of during the design, the additional work and expense will return handsomely in a better reliability and competitiveness of the final product. Integrated circuits in high level integration technologies require multilayer connecting lead systems employing high lead density and resulting in diminishing distances between individual leads. The small distances result in increased signal crosstalk inside the integrated circuit. By applying a method of crosstalk prediction in digital circuits using simple passive LCR circuit models.

  • Anotace:
    The electromagnetic compatibility serves as a measure for the possibility of co-existence of numerous electronic systems occupying a common environment without unwanted electromagnetic couplings that could interfere with correct functioning of individual systems. The microsystems, for example cardiac pacemaker, can be assumed to be independent electronic systems set up of individual operational blocks. The conveying of signals between blocks is provided by networks of electrical leads. Unwanted electromagnetic couplings do appear between leads inside the integrated circuit. During the process of signal propagation along the leads, parasitic electromagnetic couplings can cause interference in other signal leads. Such as interference can result in random disturbances in the microsystem. So, in solving the electromagnetic compatibility in microsystems, a considerable stress must be given to correct determination of parasitic electromagnetic couplings in the connecting lead systems.

Measurement of Crosstalk inside the Digital Integrated Circuit

  • Pracoviště: Katedra mikroelektroniky
  • Anotace:
    For optimum efficiency of digital systems in ICs composed of gates it is required that the changes of states of the active devices are performed as quickly as possible. The rapid variations of voltage and the resulting rapid variations of current create time-variable electric and magnetic fields around the devices and, even more important, around the connecting electric leads. Digital integrated circuits in high level integration technologies require multilayer connecting lead systems employing high lead density and resulting in diminishing distances between individual leads. The small distances result in increased signal crosstalk inside the integrated circuit.
