摘要:
Embodiments of the present invention may be used to generate oscillating signals. One embodiment of the present invention includes a circuit that receives a differential signal to be divided. The circuit converts the differential signal into an injection signal. The injection signal is coupled to an oscillator, and the oscillator generates an output signal having a frequency that is a fraction of the frequency of the differential input signal. In another embodiment, the present invention includes a MIMO wireless communication system. The MIMO system may use the divider circuit to divide a local oscillator signal with reduced common mode distortion.
