Abstract: The present invention relates to a phase interpolator for a low-power broadband transmitter and an output waveform synthesizer using an on-chip eye opening monitoring (EOM) circuit. A multiphase multiplexer driven in subrate is used for achieving both small area and low-power consumption for transmitter design. The multiphase multiplexer includes a parallel open drain NAND gate. In a structure of subrate transmitter, phase mismatching between multiphase clock signals significantly degrades a jitter performance, thus becoming a serious obstacle to supply of the subrate transmitter despite low power consumption. A waveform composition structure based on a phase interpolator having excellent area and power efficiencies is being developed for solving the mismatching problem.
