A control system to regulate the temperature of the micro hotplate in a MEMS gas sensor is presented. The controlelement, called micro hotplate, is comprised of a micro heater and a temperature sensor, both made with polysilicon, located near each other. This material has a Temperature Coefficient of Resistance (TCR) that is the basis for the design of the temperature controller of the gas sensor...
This paper describes a mixed signal approach to micro-hotplate temperature control technique using digital On-off control logic. The novel micro-hotplate used for this purpose is based on standard 600 nm CMOS technology and contains a metal micro-heater, a (parasitic) bipolar transistor temperature sensor and an interdigitated electrode in a dielectric membrane. The micro-hotplate and the mixed-signal...
In deep submicron era, to prevent larger amount of SRAM from more frequently encountered overheating problems and react accordingly for each possible hotspots, multiple ideal run-time temperature sensors must be closely located and response rapidly to secure system reliability while maintaining core frequency. This paper presented a method to extract run-time temperature information from multiple...
