Data transmission/receiving circuit, data training circuit and semiconductor apparatus including the same

Abstract

A data receiving circuit includes a first inductor, a second inductor, and a T-coil equalization circuit. The first inductor is coupled between a first node coupled with a data input/output pad and a second node. The second inductor is coupled between the second node and an internal circuit. The T-coil equalization circuit includes a T-coil with at least one capacitor coupled with the second node. The T-coil equalization circuit is configured to adjust inductive peaking of the T-coil in response to a control signal.
