This paper will demonstrate the use of momentum to model on chip spiral inductors and transmission lines. The simulation results will be compared with measured data on these structures. These modeling techniques will be extended to include an on chip balun. A method of converting the results will be given so that compact efficient models can be created that can be included in any time domain or...

An analysis of phase noise in differential crosscoupled inductance–capacitance (LC) oscillators is presented. The effect of tail current and tank power dissipation on the voltage amplitude is shown. Various noise sources in the complementary cross-coupled pair are identified, and their effect on phase noise is analyzed. The predictions are in good agreement with measurements over a large range ...

We propose the design of a reconfigurable impedance matching network for the lower RF frequency band, based on a developed RF-MEMS technology. The circuit is composed of RF-MEMS ohmic relays, metal-insulatormetal (MIM) capacitors and suspended spiral inductors, all integrated on a high resistivity Silicon substrate. The presented circuit is well-suited for all applications requiring adaptive im...

A CMOS radio-frequency power amplifier including on-chip matching networks has been designed in a 0.6m n-well triple-metal digital CMOS process, and optimized using a simulated-annealing-based custom computer-aided design tool. A compact inductor model enables the incorporation of parasitics as an integral part of the parasitic-aware design and CAD optimization; low-Q metal3 spiral inductors ar...

A completely integrated 1.8-GHz low-phase-noise voltage-controlled oscillator (VCO) has been realized in a standard silicon digital CMOS process. The design relies heavily on the integrated spiral inductors which have been realized with only two metal layers and without etching. The effects of high-frequency magnetic fields and losses in the heavily doped substrate have been simulated and model...

In this paper on-chip square spiral inductors are designed using ANN modeling techniques. Layout geometries form the input of the ANN model and electrical quantities forms the output . The dependency of inductor performances such as inductance (L), quality factor (Q) and self-resonance frequency (SRF) on geometric dimensions are described. Spirals of wide range of RF applications are studied. I...

the cúk converter, which has voltage buck and boost ability, offers high flexibility as an interface device for solar panels. in addition, current ripple can be more reduced because of two input and output inductors at both sides. this paper presents a new application of current-variable inductors in a cúk converter that reduces the size and capacity of storage elements. because of two inductor...
