Abstract :
This paper covers the development and testing of a high temperature electronics platform for integration with sensor elements to provide digital outputs that can be utilized by the FADEC (Full Authority Digital Electronic Control) system or the EHMS (Engine Health Monitoring System) on an aircraft engine. The developed system includes a reference voltage generator, biasing circuit, signal conditioning for multiple types of sensors, an Analogue to Digital converter, and an ARINC 429 transmitter for communication to the FADEC or EHMS. This system was designed and realized on 1 um Silicon-on-Insulator CMOS (Complementary Metal Oxide Semiconductor) technology and has been shown to function up to 250 degrees Celsius with low temperature coefficients for the bandgap voltage and reference current.
