VECTOR SYNTHESIS PHASE SHIFTER AND VECTOR SYNTHESIS PHASE SHIFTING METHOD

摘要

The present document provides a vector synthesis phase shifter and a vector synthesis phase shifting method. The method comprises: adjusting a first reference input excitation by means of a first current source; determining a vector direction by means of a first vector direction control circuit, sending an input to a first gate width control Circuit, and generating, by means of an adjustment made by the first gate width control Circuit, a first output signal; adjusting a second reference input excitation by means of a second current source; determining a vector direction by means of a second vector direction control circuit, sending an input to a second gate width control circuit, and generating, by means of an adjustment made by the second gate width control circuit, a second output signal; and performing vector synthesis 0n the first output signal and the second output signal.
