Abstract
PURPOSE:To suppress the phase change and the secondary harmonic distortion of output due to amplitude change in the input signal with a simple constitution, by using the differential amplifier in cascode connection of two sets of transistors. CONSTITUTION:With the cascode connection of grounded-emitter-grounded-base consisting of transistors Tr1a, 9a in the differential amplifier, the capacitance between the collector and the base of Tr1a giving effect to the input signal from the terminal 4 is equivalently made smaller. Further, with the cascade connection of grounded-emitter-granded-base consisting of Tr1b, 9b, the collector base capacitance of Tr1b giving effect on the input signal from the terminal 5 is equivalently smaller. Thus, since the capacitance between the collector and base is equivalently made smaller, even in use at the harmonics serveral MHz or more, the phase change of output and secondary harmonic distortion due to amplitude change of input signal can easily be suppressed.
