| titleOfInvention | Semiconductor pressure detector |
| abstract | PURPOSE:To provide a temperature conpensating circuit for pressure sensitivity with a linear compensating function, by compensating the sensitivity of a pressure detection bridge circuit, composed of a semiconductor gauge resistance, by parallel semiconductor gauge resistances for compensation, etc. CONSTITUTION:A supply voltage to a pressure detection bridge circuit composed of a semiconductor gauge resistance is varied by a fixed resistance R0 between the base and emitter of transistor Q and parallel compensating semiconductor gauge resistances R+DELTAR and R-DELTAR having the opposite pressure characteristics and provided between the base and collector. According to both positive and negative pressures, the supply voltage to the pressure detection bridge circuit is therefore varied as well as temperature to perform the temperature compensation of pressure sensitivity and the linear compensation of positive and negative outputs by the same circuit, so that the pressure detector has high sensitivity and simple constitution. |
