PROBLEM TO BE SOLVED: To obtain a temperature sensor whose accuracy is enhanced by a method wherein a temperature-dependent frequency signal is independent of a threshold voltage which traverses any transistor out of a plurality of transistors. SOLUTION: A microprocessor is interconnected to various components by a system bus 12. A read-only memory(ROM) 16 is connected to a CPU 10 via the system bus 12. A fundamental input/output system which controls a fundamental computer function is provided. A random access memory(RAM) 14, an I/D adaptor 18 and a communication adaptor 34 are interconnected to the system bus 12. A user performs an input operation to the system via a keyboard 24, a track ball 32 or a mouse 26 so as to receive an output from the system via a loudspeaker 28 and a display 38. |
