Abstract :
The bridged T-coil, often simply called the T-coil, is a circuit topology that extends the bandwidth by a greater factor than does inductive peaking. Many high-speed amplifiers, line drivers, and input/output (I/O) interfaces in today´s wireline systems incorporate on-chip T-coils to deal with parasitic capacitances. In this article, we introduce and analyze the basic structure and study its applications.
