Abstract
An N-stage inductor-less local oscillator (LO) buffer can include N−1 non-final stages and a final stage. The final stage can includes a gain circuit, a common-mode feedback circuit connected to the gain circuit, and a replica bias circuit that provides a predetermined voltage to the common-mode feedback circuit. The inductor-less LO buffer can advantageously reduce a power budget for its downstream mixer as well as provide a compact footprint.
