摘要
Methods and apparatus improve the signal integrity of high-speed integrated circuits. Disclosed is a passive network for an input to a receiver. One embodiment of the passive network has two coupled inductors to improve both return loss and insertion loss characteristics. A shunt inductor is connected in series with the termination resistance, while a series inductor is placed in series between the pad and receiver circuitry. By exploiting deliberately-introduced mutual coupling between these two inductors, an area-efficient passive network is created that improves both the return loss and input bandwidth.
