Low loss T-coil configuration with frequency boost for an analog receiver front end
Abstract:
Systems, apparatuses, and methods for performing efficient data transfer in a computing system are disclosed. A computing system includes multiple transmitters sending singled-ended data signals to multiple receivers. A receiver includes multiple series inductors moved from a signal path to sampling circuitry to a termination path used for impedance matching. The removed direct current (DC) resistances of the inductors in the signal path reduces signal attenuation. The termination path has alternating current (AC) reactances of the inductors, which provide a frequency-dependent termination impedance. This termination impedance provides a positive reflection coefficient for high operating frequencies, which boosts the input signal being received by the sampling circuitry.
