Abstract
An inductor-less local oscillator (LO) signal generation apparatus configured to generate one or more output signals which reduce a frequency pulling effect. The LO signal generation apparatus includes a multi-phase signal generation circuit, a phase signal generation circuit and one or more output circuits. The multi-phase signal generation circuit receives an input clock signal having a first frequency to generate a multi-phase clock signal. The multi-phase clock signal includes a plurality of clock signals each having the first frequency and different phases. The phase signal generation circuit is coupled to the multi-phase signal generation circuit to receive the multi-phase clock signal and output a plurality of phase signals indicating the phases of the clock signals. The one or more output circuits output the one or more output signals according to the clock signals and the phase signals without receiving feedback of any of the one or more output signals.
