spannungsgesteuerter lc oscillator with phaseninterpolation

摘要

A phase interpolation voltage controlled oscillator (VCO). In one embodiment, the VCO is a multiple phase interpolation VCO. The multiple phase interpolation VCO includes a plurality of phase shifting cells each receiving an oscillating signal, and each phase shifting the oscillation signal a different amount. Summing cells receive the phase shifted oscillating signals and combine the signals to determine an output oscillating signal. In one embodiment, further summing cells receive the output of other summing cells to determine the output oscillating signal.
