Some input termination networks in SerDes architectures, such as inductive-capacitive (LC) transmission‑line based structures or double T‑coil networks, offer only limited ability to extend bandwidth or control peaking. To address these challenges, an improved input termination network can be implemented. The improved input termination network includes a series impedance circuit between the T-coil network and the termination circuit. By isolating the T‑coil from the full capacitive loading of the termination circuit, the series impedance circuit significantly enhances the bandwidth and tunability of the input termination network, allowing more effective shaping of peaking and return‑loss characteristics. When combined with a parallel capacitor added to the termination circuit to stabilize high‑frequency impedance, the improved input termination network enables a more controlled and robust frequency response than other passive matching networks.
