An amplifying adder boosts PAM-4 eye size within a defined input range, enabling reliable sampling with lower comparator power.
A dual-receiver PAM eye diagram uses complementary sampling data to tune equalizer settings and offset insertion loss, noise, and ISI.
An active inductor with op-amp feedback lets a CTLE extend bandwidth and hold Nyquist peaking while cutting area and power.
Receiver feedback on unequal PAM voltage steps lets the transmitter retune drive strength and improve high-speed data recovery.
Receiver feedback detects unequal PAM voltage spacing and tunes transmitter drive strength to reduce nonlinear distortion in high-speed links.
Receiver feedback detects unequal PAM voltage spacing and tunes transmitter drive strength to reduce nonlinear distortion and improve data recovery.
A magnification parameter adjusts multiple EQ point gains at once, simplifying digital mixer equalizer tuning without losing band-level control.
Time borrowing across multi-phase sampled bits relaxes feedback-path delay, helping partial response equalizers run at higher data rates with less ISI.
