Abstract
A circuitry () adapted to operate in a high-temperature environment of a turbine engine is provided. The circuitry may include a differential amplifier () having an input terminal () coupled to a sensing element to receive a voltage indicative of a sensed parameter. A hybrid load circuitry () may be AC-coupled to the differential amplifier. The hybrid load circuitry may include a resistor-capacitor circuit () arranged to provide a path to an AC signal component with respect to the drain terminal of the switch (e.g.,) of a differential pair of semiconductor switches, which receives the voltage indicative of the sensed parameter.
