Patent ID: 7746764

Claim:
A method of generating orthogonal vectors, comprising: (a) generating, using circuitry, first and second approximately orthogonal vector signals, {right arrow over (V)} 1 and {right arrow over (V)} 4 , from a clock signal; (b) combining, using circuitry, the first and second vector signals {right arrow over (V)} 1 and {right arrow over (V)} 4 , thereby generating a vector signal {right arrow over (I)}; and (c) combining, using circuitry, an inverted version, −{right arrow over (V)} 1 , of the first vector signal {right arrow over (V)} 1 with the second vector signal {right arrow over (V)} 4 , thereby generating a vector signal {right arrow over (Q)} that is substantially orthogonal to vector signal {right arrow over (I)}.
