    摘要: A circuitry adapted to operate in a high-temperature environment of a turbine engine is provided. A relatively high-gain differential amplifier (102) may have an input terminal coupled to receive a voltage indicative of a sensed parameter of a component (20) of the turbine engine. A hybrid load circuitry may be coupled to the differential amplifier. A voltage regulator circuitry (244) 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.

    摘要: Chopper circuitry may be adapted to operate in a high-temperature environment of a turbine. A first semiconductor switch (122) may have a first terminal coupled to receive a first output signal from a first leg (148) of a differential amplifier (150). A second switch (128) may have a first terminal coupled thru a first resistive element (R1) to a second terminal of the first semiconductor switch. The first terminal of the second semiconductor switch may be coupled to receive thru a second resistive element (R2) a second output signal from a second leg (152) of the amplifier. Switches (122,128) may be responsive to a switching control signal to respective gate terminals of the switches to supply an output signal, which alternates in correspondence with a frequency of the switching control signal from a first amplitude level to a second amplitude level, which effectively provides a doubling amplification factor.
