Abstract
A well drilling system with a miniature directional indication sensor capable of operating at elevated temperature. The present invention is implemented with power supply, sensor drive and sense circuits in thick film or multi-chip module electronic assemblies, mounted on a chassis with a high resonant frequency. The thick film or multi-chip module electronics assemblies also contribute to increased shock and vibration resistance. Sensor drive and sense functions may be implemented in one or more application specific integrated circuits and integrated with multi-chip module electronics assembly. Analog-to-digital conversion of sensor signals is implemented in a voltage-to-digital converter circuit provided by the present invention. Furthermore, the present invention eliminates data lag between channels by providing simultaneous sampling of all the sensor channels.
