Differential amplifier having single phase input and two output phases |
摘要 |
A differential amplifier includes switching FETs provided at an input side and at a reference side, respectively, forming a differential pair; an FET serving as a constant current source for providing a current flow equal to a sum of the currents flowing through the respective switching FETS; and an inductor connected in series to the FET serving as a constant current source between the connection node of both switching FETs and the power supply of the amplifier. The inductor is not a load with respect to DC and any fluctuation of the signal current flowing through the FET serving as a constant current source is small so that any difference between the output voltages at two different phase outputs is reduced.
