IQ GENERATOR FOR MIXER

An IQ generator capable of consuming lower power and occupying smaller die area. The IQ generator is configured without any synthesizer and divide-by-2 circuitry. The IQ generator may be configured to convert one or more phase outputs of a test tone generator (TTG) into I and Q signals. The IQ gener...

More Information
Summary:An IQ generator capable of consuming lower power and occupying smaller die area. The IQ generator is configured without any synthesizer and divide-by-2 circuitry. The IQ generator may be configured to convert one or more phase outputs of a test tone generator (TTG) into I and Q signals. The IQ generator may receive as inputs differential outputs of a single phase of a TTG and/or multiple phase outputs of a TTG. The IQ generator may include one or more delay paths configured to generate the I and Q signals, and a calibration circuitry configured to compare the average pulse widths of the I and Q signals and provide one or more control signals to the one or more delay paths such that the I and signals are orthogonal in phase.
