Title: Method and circuit to generate sinusoids for modulators and frequency converters
Inventor: SAHOTA GURKANWAL S
IPC: H03B27/00
Filed: 2001-10-09
Granted: 2004-01-11
Abstract: A signal generator includes first and second mixers, first and second phase shift networks, and a summer. The first and second mixers respectively receive and mix a quadrature and an inphase sinusoid at a first frequency with a second input sinusoid at a second frequency. The first and second phase shift networks respectively couple to the first and second mixers, receive the outputs from the first and second mixers, and generate first and second phase shifted signals. The summer couples to the first and second phase shift networks and receives and sums the first and second phase shifted signals to generate a first output sinusoid. A second summer may be coupled to the first and second phase shift networks to receive and sum third and fourth phase shifted signals (generated by the first and second phase shift networks, respectively) to generate a second output sinusoid. The first and second output sinusoids are in quadrature. A third phase shift network may be adapted to receive a first input sinusoidal at the first frequency and generate the inphase and quadrature sinusoids.
