Abstract
A novel non-orthogonal vector summing method is
proposed and used to design phase shifter (PS) with low phase
error and high phase resolution. The principle and topology of
the proposed method are first investigated, while the calculation
results indicate less sensitivity from phase error to magnitude
mismatch than the conventional orthogonal vector summing
method. A non-orthogonal vector generator with low phase
and magnitude error is further designed to implement the
proposed non-orthogonal vec
