Abstract: A differential amplifier circuit is provided. The differential amplifier circuit includes a differential amplifier, a first active inductor, a second active inductor, and a parameter circuit. The differential amplifier includes a first differential output terminal and a second differential output terminal. The first active inductor is coupled to the first differential output terminal. The second active inductor is coupled to the second differential output terminal. The parameter circuit is coupled between the first active inductor and the second active inductor. The parameter circuit provides at least one parameter. A low frequency gain, an equivalent impedance, and a bandwidth of the differential amplifier circuit are adjusted in response to the at least one parameter.

Abstract: A transmission circuit is provided. The transmission circuit includes a T-coil, a first resistance value generator, a second resistance value generator and a capacitance value generator. The first resistance value generator generates a first resistance value according to a first control signal. The second resistance value generator generates a second resistance value according to a second control signal. The capacitance value generator generates a capacitance value according to a third control signal. A gain spectrum of the transmission circuit is adjusted according to the first resistance value, the second resistance value and the capacitance value.
