Abstract
A circuit for generating a component of n-th order includes: six differential amplifiers (A toF) having a pair of input terminals supplied with a common linear input signal and a constant level signal of a predetermined level, outputting a reversed or non-reversed signal to the linear input signal, and having a limiter function to limit the output signal to a predetermined maximum value and a minimum value; a constant level signal generation circuit for supplying the constant level signal to each of the six differential amplifiers; a current mirror circuit () for controlling current flowing in the differential amplifiers (A toF); and addition resistors (A,B) for adding the output current of the differential amplifiers (A toF). By increasing the flowing current by the sixth differential amplifier (F) so as to increase the resistance value, it is possible to obtain a highly accurate output current of a component of a 5-th order function having more precipitous inclination with respect to the input signal.
