Abstract:
1. A method for minimizing ringing in a high speed channel between a transmitter and a receiver in a circuit, comprising: receiving a plurality of signals from the transmitter to the receiver via the channel, wherein each signal of the plurality of signals comprises a plurality of pulses representing a bit stream; aggregating the plurality of received signals into an aggregate voltage signal comprising a main cursor pulse and a plurality of jitter pulses, wherein each jitter pulse of the plurality of jitter pulses comprises a lesser magnitude than the main cursor pulse; determining a voltage magnitude and a time for each of the plurality of jitter pulses; and initializing an n-tap equalization filter comprising a plurality of taps, wherein each tap of the plurality of taps is associated with at least one jitter pulse of the plurality of jitter pulses, equalizing a test signal over the channel with the n-tap equalization filter; modifying at least one voltage magnitude of at least one of the plurality of taps to minimize an amount of jitter from the test signal; and
