Abstract
There is provided a highly linear differential amplifying circuit. The highly linear differential amplifying circuit includes: a differential amplifying unit including a main differential amplifying unit having a differential pair of transistors for amplifying a difference of two input signals and an auxiliary amplifying unit connected in parallel with the main differential amplifying unit, wherein second-order derivatives of transconductances of the main differential amplifying unit and the auxiliary differential amplifying unit are properly set to have an offset; and a source degeneration resistor unit including a first source degeneration resistor to a fourth source degeneration resistor. Accordingly, the linearity of the differential amplifying circuit is improved at a wide output power region.
