Design and analysis of CMOS-based terahertz integrated circuits by causal fractional-order RLGC transmission line model
A causal and compact fractional-order model is developed for complementary metal–oxide–semiconductor (CMOS) on-chip transmission line (T-line) at Terahertz (THz) frequencies. With consideration of the loss from frequency-dependent dispersion and nonquasi-static effects at THz, good agreement of...

| Summary: | A causal and compact fractional-order model is developed
for complementary metal–oxide–semiconductor (CMOS)
on-chip transmission line (T-line) at Terahertz (THz) frequencies.
With consideration of the loss from frequency-dependent dispersion
and nonquasi-static effects at THz, good agreement of characteristic
impedance is observed between the proposed fractionalordermodel
and the measurement up to 110 GHz, while traditional
integer-order model can only match up to 10 GHz. The developed
fractional-order model is further deployed in the design and analysis
of CMOS-based THz integrated circuits that utilize T-line,
such as standing-wave oscillator, which has significantly improved
accuracy with causality. |
