Abstract

The invention discloses a millimeter-wave frequency multiplier and cascaded frequency multipliers, belonging to the technical field of radio frequency/millimeter wave integrated circuits. The frequency multiplier provided by the invention comprises a pseudo-differential amplifier, an LC parallel resonator cavity and an LC series resonator cavity, wherein the LC parallel resonator cavity is connected between the output end of the pseudo-differential amplifier and a power supply VDD (Voltage Drain Drain), the LC series resonator cavity is connected between the output end of the pseudo-differential amplifier and a ground wire, both input ends of the pseudo-differential amplifier are respectively connected with the positive end and the positive end of an input baseband signal (f0); and the LCparallel resonator cavity has the resonation frequency of 2f0, and the LC series resonator cavity has the resonation frequency of 4f0. The cascaded frequency multipliers provided by the invention comprise a plurality of the frequency multipliers which are sequentially connected through a single-to-double passive transformer. The millimeter-wave frequency multiplier and the cascaded frequency multipliers, provided by the invention, have the advantages of low power consumption, pure frequency spectrum of a frequency-multiplication output signal, good harmonic suppression performance, strong output signal, high frequency and easiness for single-chip integration on a silica-based process.
