Title:
関数発生回路および関数発生回路の温度特性調整方法
Document Type and Number:
Japanese Patent JP4044027
Kind Code:
B2
Abstract:
In a function generating circuit which comprises a temperature sensor 1 for outputting an output current (Ilin) with a linear temperature characteristic or an output voltage (Vlin) with the linear temperature characteristic, a cubic function generating circuit 2 for receiving the output current (Ilin) or the output voltage (Vlin) of the temperature sensor 1 as an input and generating a cubic temperature characteristic voltage (Vcub), and a control data storing circuit 3 for recording control data to control the output characteristic of the cubic function generating circuit 2 , an external control signal is applied to the temperature sensor 1 from an external control terminal 4 to cause the sensor to output variably the output current (Ilin) or the output voltage (Vlin) such that the temperature characteristic of the cubic function generating circuit 2 can be controlled at the ordinary temperature.
