A computationally efficient physics-based wideband predictive inductor compact model is presented that is capable of evaluating the impact on inductance and quality factor of dummy metal fill-cells. In a modern integrated-circuit process, high amount

Solid-state varactor performance is evaluated in light of fundamental tradeoffs imposed by semiconductor material. This leads to the important conclusion that the product of Q factor, frequency, tuning range, and breakdown voltage has an upper limit

A new noise-figure measurement method, which combines the simplicity of the "classical" Y-factor method with the accuracy of the widely used "cold noise-source" method, is reported. Implemented in our fully automated wide-band 1-18-GHz on-wafer noise

The impedance errors remaining after applying the industry standard "open-short," a "pad-open-short," and a "open-short-load" deembedding scheme on a 0.43-nH 20-GHz high-Q single-loop inductor test structure are investigated using real S-parameter da

This paper presents a new method, developed for the capacitance–voltage (C–V) characterization of leaky dielectrics. The method comprises measurements in the gigahertz range on specially designed RF test structures. The method is verified against

The RF noise in 0.18-/spl mu/m CMOS technology has been measured and modeled. In contrast to some other groups, we find only a moderate enhancement of the drain current noise for short-channel MOSFETs. The gate current noise on the other hand is more

The impedance errors remaining after conventional de-embedding for a high-speed transistor and a single-loop inductor test structure are investigated. A new de-embedding strategy using a physics-based lumped-element model for the test-structure paras

The collector epilayer is a crucial element in the behavior of modern bipolar transistors. Compact models for its description, like the Kull model, are therefore of crucial importance too. We give a Mextram-based improvement to these models for quasi

The performance of inductors realized in various metal layer combinations available in an advanced CMOS process with a mixed copper-aluminum backend is compared. Due to the skin effect, the gain in performance is generally smaller than anticipated fr

We present a MOS Capacitance-Voltage measurement methodology that, contrary to present methods, is highly robust against gate leakage current densities up to 1000 A/cm/sup 2/. The methodology features specially designed RF test structures and RF meas
