The (bridged) T-coil is a circuit topology that extends signal bandwidth.
A bridged T coil is a circuit configuration with a capacitor from input to resistive load and extends signal bandwidth (as does an unbridged T coil). The bridged T coil can also turn a complex load impedance such as an RC or a series RLC into a purely resistive load at all frequencies. A regular (not bridged by a capacitor) T coil cannot do the latter.
