ABSTRACT:
A temperature compensation circuit having satisfactory linearity, a trimming circuit including a plurality of temperature gradients, and an acceleration detector having a wide applicable temperature range. A plurality of resistor elements R1to R4, R5to R8, R21to R24, R25to R28are connected in series between a power supply voltage line and a ground voltage line. Resistor elements R9to R14are connected in series between connection nodes N1and N3. Resistor elements R29to R34are connected in series between connection nodes N2and N4. The resistor elements R1, R2, R4, R5, R7to R14, R24, R25have negative temperature coefficients. The resistor elements R3, R6, R21to R23, R26to R34have positive temperature coefficients. An output terminal NT5connects a connection node of the resistor elements R13and R14and a connection node of the resistor elements R30and R29.
