Abstract
A pseudo-cubic function generator circuit comprises a CMOS inverter which is applied with a detected voltage of a sensor and supplied with a power supply voltage, and a voltage divider circuit for dividing the power supply voltage, wherein an output terminal of the CMOS inverter is connected to a voltage division point of the voltage divider circuit to generate an output voltage from the voltage division point. The pseudo-cubic function generator circuit can directly generate a large voltage change in a simple circuit configuration with a reduced noise component, and facilitates a setting of each parameter for specifying a cubic function curve. The parameter is set, for example, by scaling substantial gate areas of a P-MOS FET and an N-MOS FET which constitutes the CMOS inverter.
