Classification: CPC G  H | IPC G  H

Claim 8:
9. A method of operating a transmitter circuit to generate a serial signal from parallel signals, the method comprising:
generating first clock signals having different respective phases in response to a reference clock signal;
sequentially outputting the parallel signals by simultaneously driving an output node using at least two selection circuits among a plurality of selection circuits, wherein each of the at least two selection circuits operates in response to at least one of the first clock signals and receives at least two of the parallel signals; and
generating the serial signal by amplifying a signal at the output node,
wherein each selection circuit of the at least two selection circuits comprises:
a first P-type transistor configured to precharge the output node in response to detecting a first parallel signal among the parallel signals having a first logic level and a second parallel signal among the parallel signals having the first logic level; and
a first N-type transistor configured to discharge the output node in response to detecting the first parallel signal having a second logic level and a second parallel signal having the second logic level.
