This paper reports a half-rate bang-bang clock and data recovery (BBCDR) circuit supporting the trimodal (NRZ/PAM-4/PAM-8) operation. The observation of their crossover- points distribution at the ...

Convolution weights are locally stored as 4-bit digital values. The circuit has been synthesized in 110 nm CMOS technology. For this configuration, the simulation results show that the circuit is able ...
