HYBRID LOAD DIFFERENTIAL AMPLIFIER OPERABLE IN A HIGH TEMPERATURE ENVIRONMENT OF A TURBINE ENGINE
摘要
A circuitry (120) adapted to operate in a high-temperature environment of a turbine engine is provided. The circuitry may include a differential amplifier (122) having an input terminal (124) coupled to a sensing element to receive a voltage indicative of a sensed parameter. A hybrid load circuitry (125) may be AC-coupled to the differential amplifier. The hybrid load circuitry may include a resistor-capacitor circuit (134) arranged to provide a path to an AC signal component with respect to the drain terminal of the switch (e.g., 128) of a differential pair of semiconductor switches 126, 128, which receives the voltage indicative of the sensed parameter.
