LOCAL OSCILLATOR BALLOON USING INVERTING CIRCUIT

摘要

PURPOSE: A local oscillator balloon using an inverting circuit is provided to improve the driving amplitude and reduce a phase difference between two complementary outputs by using the inverting circuit. CONSTITUTION: A local oscillator balloon using an inverting circuit includes a complementary output conversion circuit(21), a differential amplification circuit(22), and an inverting circuit(24). The complementary output conversion circuit is used for receiving and amplifying a weak signal from a local oscillator to output two complementary signals. The differential amplification circuit is used for outputting two signals having the predetermined amplitude according to the complementary signals of the complementary output conversion circuit. The inversion circuit is used for inverting the output signals of the differential amplification circuit and outputting the inverted signals.
