DOI: 10.1109/jssc.2024.3516197
Abstract: This article presents a six-phase cell-reused digital transmitter (DTX) using 1/3 duty-cycle local oscillator (LO) signals for harmonic rejection. The 1/3 duty-cycle square wave ideally generates no 3rd-order component, thus facilitating the on-chip method to… read more here.
