Description
Summary:A 96-GHz CMOS oscillator is demonstrated in this brief with the use of a high-[Formula Omitted] metamaterial resonator. The proposed metamaterial resonator is constructed by a differential transmission line (T-line) loaded with complementary split-ring resonator engraved on the T-line. A negative real part of permittivity, i.e., [Formula Omitted], is observed near the resonance frequency, which introduces a sharp stopband and, thus, leads to a high- [Formula Omitted] resonance. This brief is the first in literature to explore CMOS on-chip metamaterial resonator for oscillator design at the millimeter-wave frequency region. Compared with the existing oscillators with a [Formula Omitted]-tank-based resonator at around 100 GHz, the proposed 96-GHz oscillator with high-[Formula Omitted] metamaterial resonator shows much lower phase noise of [Formula Omitted]111.5 dBc/Hz at 10-MHz offset and figure-of-merit of [Formula Omitted]182.4 dBc/Hz.
