ABSTRACT:
A complementary differential amplifier comprises a first differential amplifier circuit having first conductivity type differential transistors and a second differential amplifier circuit having second conductivity type differential transistors. To improve a dynamic range and a slew rate of the complementary differential amplifier and, to prevent of the generation of TIM distortion with a simple construction, a constant voltage circuit is connected between commonly connected electrodes of differential transistors of the first differential amplifier circuit and commonly connected electrodes of differential transistors of the second differential amplifier circuit. To improve a slew rate in a high frequency range and to prevent the generation of TIM distortion, a capacitor may be connected between the commonly connected electrodes of the differential transistors of the first differential amplifier and the commonly connected electrodes of the differential transistors of the second differential amplifier.
