operable hybrid load differential amplifier in a high-temperature environment of the turbine engine

摘要

circuit (120) that has been adapted to operate in high temperature environment of the turbine engine is provided. Circuit, in order to receive a voltage indicative of the sensed parameters may include a differential amplifier (122) having coupled input terminals on the sensing element (124). Hybrid load circuit (125) may be AC coupled to the differential amplifier. Hybrid load circuit includes a switch of the semiconductor switch 126, 128 of the differential pair (eg, 128) arranged resistance capacitance circuit so as to provide a path to an AC signal component in relation to the drain terminal of the (134) , it may receive a voltage indicative of the sensed parameter.
