Abstract
A three-level pulse amplitude modulation (PAM-3)
transceiver (TRX) with improved simultaneous switching out-
put (SSO) noise and reference voltage margin was studied. PAM-3
signaling with an insertion of 3 bits in 2-unit intervals (UI) was
implemented using the upper, under, and ground voltages, achiev-
ing 150% pin efficiency. The ground-referenced signaling (GRS)
charge pump driver reduced SSO noise and maintained ground
as the solitary return current path. Capacitive peaking and
