HIGH FREQUENCY SIGNAL GENERATOR USING RF NEGATIVE RESISTANCE CIRCUIT WITH COMPLEMENTARY CROSS-COUPLED OSCILLATOR TOPOLOGY

摘要

The present invention relates to a high frequency signal generator using a CMOS process. The high frequency signal generator of the present invention includes an RF negative resistance circuit and a complementary oscillator cross-coupled with the RF negative resistance circuit. The RF negative resistance circuit comprises a first inductor and a pair of RF negative resistance transistors. The RF negative resistance transistors are an N-channel metal oxide semiconductor (NMOS) where a drain is connected to a power source, the gate is connected to both ends of the first inductor, and a source is connected to the complementary oscillator. According to the present invention, a high frequency signal generator is realized by using a complementary oscillator structure cross-coupled with an RF negative resistance circuit. Thereby, high oscillation frequency can be generated.
