Abstract
PURPOSE:To reduce higher harmonic distortion, by limiting amplitude when the differential signal of an input signal exceeds a preset value, and integrating and outputting a limited signal. CONSTITUTION:When the amplitude level of the input signal is less than a limiter level, the characteristic of the differential pairs of transistors Q11 and Q12 in a limiter circuit becomes a linear amplification characteristic, and a frequency characteristic between input and output is almost flattened between the cut-off frequency of a differentiation circuit consisting of a capacitor C2 and a resistor R3 and the cut-off frequency of the differentiation circuit consisting of a capacitor C1 and a resistor R1. Next, when the amplitude level of the input signal exceeds the limiter level, the transistors Q11 and Q12 show a non-linear amplification characteristic, the input signal enters a limiter area. At this time, since an output signal is integrated by the integration circuit consisting of the resistor R3 and the capacitor C2, a higher harmonic component is attenuated, then, the higher harmonic distortion can be reduced.
