The differential (symmetric) inductor is useful for its higher Q factor and smaller area than a single-end inductor in silicon-based RFIC. The limitations are the inductance value and the inductor track width. Large inductance or track width often results in too high overall capacitances and too large an area.

Spinal congenital dermal sinus (CDS) is a rare entity which supposedly results from the failure of the neuroectoderm to separate from the cutaneous ectoderm during the process of neurulation. The lesions are most frequent at the lumbosacral followed by the occipital region. CDS of the thoracic region is very rare. The patients with spinal CDS present with(More)
Slow-wave structures using distributed periodic inductive and capacitive loadings have found many microwave circuit applications as left-handed (bandpass) or right-handed (low-pass) transmission lines. A large slow-wave factor (SWF) could result in a much smaller passive component, but also a much lower bandgap (cutoff) frequency and a larger dispersion.(More)
In this paper, we present the design and analysis of an on-chip transformer balun for silicon RFICs. Both the primary and secondary spread over four metal layers along a common symmetric axis to reduce the overall area, maintaining reasonable quality factor. A five port transformer balun circuit model is developed to facilitate the device simulation. A 4:11(More)
