Abstract
A circuitry adapted to operate in a high-temperature environment of a turbine engine is provided. A relatively high-gain differential amplifier () may have an input terminal coupled to receive a voltage indicative of a sensed parameter of a component () of the turbine engine. A hybrid load circuitry may be coupled to the differential amplifier. A voltage regulator circuitry () may be coupled to power the differential amplifier. The differential amplifier, the hybrid load circuitry and the voltage regulator circuitry may each be disposed in the high-temperature environment of the turbine engine.
