This paper reports a first attempt toward realization of a single-chip silicon-based broadband (BW-3dB > 5 GHz) low-noise amplifier (LNA) with a noise figure (NF) of less than 1 dB across the band. A differential common-emitter amplifier with active feedback and neutralization capacitance is adopted without using passives at the input that consume chip area and deteriorate NF due to ...

This paper presents the design and analysis of a 60-GHz 0.13-mum CMOS divide-by-three frequency divider (FD). The regenerative injection-locked technique is proposed to achieve divide-by-three function at millimeter-wave frequency. The novel level shifter is used to increase the overdrive voltage of the input switch of the loop divider such that the divider locking range and input sensitivity can ... View full abstract»

This paper addresses the theoretical aspects of passive intermodulation (PIM) generation in printed transmission lines. In order to elucidate the mechanisms of PIM generation, a new model of the transmission line length with distributed nonlinearity is proposed. The developed model has been validated by the near-field measurements of PIM product distributions along the microstrip lines. The contri... View full abstract»

• Stability and Passivity Enforcement of Parametric Macromodels in Time and Frequency Domain

Publication Year: 2008, Page(s):2435 - 2441

| | PDF (1639 KB) | HTML

This paper presents a robust technique for the macromodeling of time-domain and frequency-domain responses, which are parameterized by one or more design variables. The representation of the multivariate macromodel ensures that stability of the transfer function poles is enforced by construction. Passivity of the parametric macromodel can be enforced in a post-processing step by perturbation of ba... View full abstract»

| | PDF (1449 KB) | HTML

In this study, a two-stage simulation method is presented for the efficient design of frequency dividers using harmonic balance. The first stage uses a modified conversion matrix approach to select the subharmonic loads of the active element enabling the frequency division by a given order N. The second stage makes use of an auxiliary generator to obtain and modify the sub-harmonic-power cu... View full abstract»

A new technique, called statistical neuro-space mapping, is proposed for large-signal statistical modeling of nonlinear microwave devices. The proposed technique is an advance over a recent linear statistical mapping technique. It uses nonlinear mapping to overcome the accuracy limitations of the linear mapping in modeling large statistical variations among different devices. For a given populatio... View full abstract»

• Novel Tunable Bandpass Filter Realized Using Barium–Strontium–Titanate Thin Films

Publication Year: 2008, Page(s):2468 - 2473

| | PDF (1070 KB) | HTML

A novel three-pole electrically tunable narrow bandpass filter has been fabricated from bi-layer YBCO/Ba0.05Sr0.95TiO3 thin films. At 77 K, and without bias, the filter has a center frequency of 3.50 GHz and 5.8% bandwidth. Independent application of dc bias to each of the resonators of 120, 182, and 100 V shifted the center frequency to 3.68 GHz. The insertion los... View full abstract»

• Balanced-to-Unbalanced Bandpass Filters and the Antenna Application

Publication Year: 2008, Page(s):2474 - 2482

Novel balanced-to-unbalanced (balun) bandpass filters are presented and carefully examined. By properly converting a symmetric four-port balanced-to-balanced bandpass filter to a three-port device, with two ports forming a balanced output and one port remaining unbalanced, a novel three-port balun bandpass filter with both functions of balun and bandpass filter may be realized. Specifically, a bal... View full abstract»

We propose a generalized T -matrix definition that facilitates the conversion between the S-parameter and T-parameter for multiport networks based on the well understood and mathematically simple two-port relations. This approach generalizes all multiport networks into two cases: balanced and unbalanced. Balanced networks have the same number of entrance and exit ports and are... View full abstract»

Aims & Scope

The IEEE Transactions on Microwave Theory and Techniques focuses on that part of engineering and theory associated with microwave/millimeter-wave components, devices, circuits, and systems involving the generation, modulation, demodulation, control, transmission, and detection of microwave signals. This includes scientific, technical, and industrial, activities. Microwave theory and techniques relates to electromagnetic waves usually in the frequency region between a few MHz and a THz; other spectral regions and wave types are included within the scope of the Society whenever basic microwave theory and techniques can yield useful results. Generally, this occurs in the theory of wave propagation in structures with dimensions comparable to a wavelength, and in the related techniques for analysis and design..
