Abstract
In at least some embodiments, a tool may comprise a tool body and one or more tool components. The tool may further comprise tool electronics located within the tool body, wherein the tool electronics are operable to sense and store tool component characteristics and environmental characteristics. At least some of the tool electronics are operable, at least for one week, when exposed to temperatures of at least 200 Celsius. The tool electronics may be integrated circuits formed on a silicon carbide substrate or a silicon on sapphire substrate. One illustrative embodiment of the tool is a drill bit for employment in a high temperature drill well.

A tool, comprising:
- a tool body;
- tool electronics located within the tool body, wherein the tool electronics are operable to sense at least one characteristic from a group consisting of tool component characteristics and environmental characteristics, and are further operable to transmit the sensed characteristic to a tool operator interface remotely located with respect to a location of the tool,
- wherein at least some of the tool electronics are operable when exposed to temperatures of at least 200 Celsius,
- wherein the integrated circuit is selected from the set of circuits consisting of analog-to-digital converters, digital-to-analog converters, operational amplifiers, digital logic gates, voltage references, oscillators, anti-fuse memories, state machines, floating poly-to-poly memories, microprocessors, micro electromechanical systems (MEMS), tag sensors, DC/DC voltage converters, digital memory, analog memory, processors, on-chip transformers, on-chip inductors, on-chip capacitors, on-chip resistors, programmable logic devices (PLDs), mixers, switches, and charge pumps.
A method, comprising:
