  • Publication number: 20230353431
    Abstract: A low power PAM-4 output transmitter is disclosed. The lower power PAM-4 output transmitter comprises a first source series terminated SST branch configured to include unit cells having transistors which are selectively activated in response to an input signal outputted from an encoder; a second SST branch configured to include unit cells having transistors which are selectively activated in response to a negative signal of the input signal; and a common voltage switch H3 configured to short or open the first SST branch and the second SST branch. Here, differential signals are outputted from both terminals of the first SST branch and the second SST branch by making the first SST branch and the second SST branch short or open according to an operation of the common voltage switch.
