Abstract

This thesis presents novel Temperature-to-Digital Converters (TDCs) designed and fabricated in CMOS technology. These integrated smart temperature sensing circuits are widely employed in the Micro-Electro-Mechanical Systems (MEMS) field in order to mitigate the impact of the ambient temperature on their performance. In this framework, the increasingly stringent demands of the market have led the cost-effectiveness specification of these compensation solutions to an higher and higher level, directly translating into the requirement of more and more compact designs (< 0.1 mm²); in addition to this, considering that the great majority of the systems whose thermal drift needs to be compensated is battery supplied, ultra-low energy-per-conversion (< 10 nJ) is another requirement of primary importance. This thesis provides a detailed description of two different test-chips (mas fuerte and es posible) that have been designed with this orientation and that are the result of three years of research activity; for both devices, the conception, design, layout and testing phases are all described in detail and are supported by simulation and measurement results.
