  • Polyphase filters in silicon integrated circuit technology
    Patent number: 6696885
    Abstract: An IQ generator is integrated into an IC for generating IQ output signal. The IQ generator includes a signal generator providing input with two identical signals opposed in phase, a filter comprises a plurality capacitances and inductances, and output providing the I and Q signals. The capacitances and inductances of the filter are integrated into said integrated circuit.
