Features a 12-bit digital readout using sigma-delta A/D converter
February 18, 2008 -- Bangalore, India and Gilroy, California -- Cosmic Circuits today introduced a silicon-proven temperature sensor in the 65nm TSMC process. The temperature-sensor comes with an integrated 12b sigma-delta Analog-to-Digital converter to provide an accurate digital readout.
Today’s System-on-Chip devices in 65nm process technology integrate multiple systems on the same chip. The level of complexity and integration often results in increase in die-temperature. Systems that push performance or work in harsh high-temperature environments need capability to track the temperature. “Availability of a proven temperature sensor silicon IP core in 65nm effectively addresses this need, and enables value-added capabilities on our customers’ system-on-chipsâ€, said Krishnan Ramabadran, VP of Marketing for Cosmic Circuits.
Commenting on the technical aspects of the temperature sensor, C. Srinivasan, VP of Engineering for Cosmic Circuits said that “the sensor comes with an integrated analog-to-digital converter based on the sigma-delta architecture that does not compromise with the accuracy. With a direct 12-bit readout, it aids easy integration to a host microprocessor busâ€, and further added that “it is configurable up to 8-sensors while using the same digitizer, and a complete die temperature profiling is possible with minimal impact to the die-areaâ€.
Other features include a power-down capability with short wake-up times enabling less than 2uA of average current drawn from the supply. The power-supply range is wide, ranging from 2.7V to 4.2V, providing flexibility and tolerance to wide power-supply variations. The sensor can be connected directly to a Li-Ion battery at 4.2V.
The IP-core is available today for integration into customer chips. Cosmic Circuits works closely with its customers for appropriate integration of silicon-IP and thus ensure first-pass success for its customers.
