VOLTAGE REGULATOR CIRCUITRY OPERABLE IN A HIGH TEMPERATURE ENVIRONMENT OF A TURBINE ENGINE
摘要
A voltage regulator circuitry (50) adapted to operate in a high-temperature environment of a turbine engine is provided. The voltage regulator may include a constant current source (52) including a first semiconductor switch (54) and a first resistor (56) connected between a gate terminal (G) and a source terminal (S) of the first semiconductor switch. A second resistor (58) is connected to the gate terminal of the first semiconductor switch (54) and to an electrical ground (64). The constant current source is coupled to generate a voltage reference across the second resistor 58. A source follower output stage 66 may include a second semiconductor switch (68) and a third resistor (58) connected between the electrical ground and a source terminal of the second semiconductor switch. The generated voltage reference is applied to a gating terminal of the second semiconductor switch (58)
