    摘要: A capacitance acceleration sensor and method of making same are disclosed. A capacitance acceleration sensor includes a movable electrode etched from a silicon plate which is clamped between two solid dielectric plate members of glass, silicon oxides, or oxygen oxides. Static electrodes are secured to surfaces of the dielectric members facing opposite the movable electrode, thereby providing easy manufacturing assessibility for leadout wires from these electrodes. In certain embodiments, the movable electrode is formed integrally with a monocrystalline silicon plate member which also contains an integrated circuit for generating an output acceleration signal in response to movement of the movable electrode when the assembly experiences acceleration forces.

    摘要: A pressure transducer comprises a pressure sensor including a bridge connection of gauging resistors formed on a semiconductor substrate, and a power supply connected to the pressure sensor for driving it and basically acting as a constant current source. The power supply includes at least two transistors formed on the semiconductor substrate. One of the transistors provides a collector current which is less in temperature-dependency relative to that of the other transistor, and the other transistor has a collector circuit connected to the pressure sensor and provides a collector current corresponding to a sum of a substantially temperature-dependent current and a substantially temperature-independent current. A ratio of the temperature-dependent current to the temperature-independent current is adjusted by selecting operation characteristics of the two transistors such that a temperature characteristic of the collector current of the other transistor is substantially inversely proportional to a temperature characteristic of the output of the pressure sensor when it is driven with a constant voltage.
