Patent ID: 11838152

Abstract:
A semiconductor integrated circuit includes a substrate including a first wiring layer and a second wiring layer that is separated from the first wiring layer in a stacking direction, and an equalization circuit formed on the substrate to amplify a signal level of a part of a frequency bandwidth included in a differential input signal including a first signal and a second signal, and output a differential output signal including a third signal and a fourth signal, in which the equalization circuit includes a first transistor, a first inductor element, a second transistor, and a second inductor element, each of the first inductor element and the second inductor element has a first inductor portion, a second inductor portion, and a third inductor portion, the first inductor portion and the second inductor portion include single-layer winding coils, a third end portion of the third inductor portion is electrically connected to a first end portion of the first inductor portion, and a fourth end portion of the third inductor portion is electrically connected to a second end portion of the second inductor portion.
