Overheat protection circuit for high frequency processors

Abstract

Abstract. The paper describes design and structure of the overheat protection circuit based on the PTAT sensors. The digital core of the system is driven by a 3-bit information generated by the structure. As a result, behaviour of the core differs for each temperature. The circuit was designed in LF CMOS 0.15 µm technology using full-custom technique. The presented paper focuses especially on the structure of the overheat protection circuit and simulations results of the functional blocks of the system. Layout and some parameters of the circuit are also considered.

Probabilistic elements in analysis of performance of multiprocessor systems

“…We should supply proper solutions to limit this disadvantageous phenomenon. For example, in one of the solutions we can use proper sensors to monitor temperature of the cores of a multi-core processor [20].…”

Investigation of Heat Transfer in Integrated Circuits

“…That means that monitoring and controlling chip temperature becomes necessary. Some real-time systems achieving that goal have already been developed [3]. The main aim of the paper is to present, explain and illustrate the case of the thermal inertia phenomenon when the temperature of some parts of the integrated circuit is still rising despite no active heat sources.…”
