The effects of through-silicon via (TSV) depletion are analyzed based on the frequency- and time-domain measurements in this paper. As TSV dc bias voltage increases, a TSV depletion region is generated; this region decreases TSV noise coupling at frequencies below 1 GHz. It also creates duty-cycle distortion of the coupled signal, which results from the nonlinearity of the TSV.

A methodology is presented for the computationally-efficient and accurate rational approximation of broadband electromagnetic responses of passive multi-ports. The proposed method relies on the repeated rational interpolation of subsets of the frequency data with the number of samples in each set being a fraction of that in the original set. The generated poles from the subsets are appropriately combined to serve as the poles of the multi-port system and to solve for the residues of its rational function fit. The expediency of this methodology is demonstrated through its application to the fitting of several multi-port broadband data.

High frequency supply noise affects chip performance in mechanisms that go beyond logic path failures due to voltage drops. One of the dominant chip performance degradation mechanisms due to high frequency noise is the direct introduction of clock jitter. Basic modeling studies powered by Fourier analysis help establish a clear and fundamental understanding of how noise is translated into jitter in the clock distribution path. In this context oscillator feed forward mechanism is also explored and analysis of its spectral response reveals how, once tuned properly, it benefits frequency boost.

This work proposes two noise reduction schemes that use strongly coupled vertical-turn traces as substitute for weakly coupled vertical-turn traces and added guard traces to reduce the common-mode noise in a weakly differential serpentine delay microstrip line. The peak-to-peak amplitude of common-mode noise in the time-domain is reduced by bout 65% using the two methods, according to simulation results. The simulation results demonstrate that the frequency range over which the magnitude of differential-to-common mode conversion is reduced for a differential serpentine delay line with is wide band in the range 0.1∼2.7GHz and 3.2∼10GHz. Furthermore, the differential reflection loss for additional guard traces is only slightly reduced at the frequency of interest, but when strongly coupled vertical-turn traces are used. However, the differential insertion loss achieved using the two improved schemes is almost the same as that of the traditional pattern.

A parallel computation approach based on the properties of the Graphics Processor Units (GPU) is here presented to speed-up the broadband modeling of passive 3D structures. The full-wave electromagnetic model is based on a surface integral formulation, numerically implemented by using a null-pinv decomposition of the unknowns. The numerical model has been proven to be accurate and well-posed for a frequency range from DC to hundreds of GHz. A bottleneck of the model is the assembly of fully populated matrices and the final matrix inversion. This paper presents A GPU parallelization of the matrix assembly phase, and analyzes two case-studies which refer to full-wave analysis of interconnects. The achieved speedup with respect to a conventional serial approach is around 50x.

As TSV-based three-dimensional integrated circuit (3D IC) technology advances rapidly, research on a new scheme for a three-dimensional clock distribution network (3D CDN) in TSV-based 3D IC with low skew, low jitter, low power consumption and small area consumption is needed. In this paper, we propose a new 3D CDN structure with distributed multi-TSV 3D CDN (DMT 3D CDN), and analyze the skew, jitter, power and area consumption. The proposed DMT 3D CDN improves the performance of the skew, jitter and area consumption, although the power consumption is degraded.

In this paper, we introduce a new decoupling capacitor stacked chip (DCSC) with discrete capacitors and through-silicon-vias (TSVs) that can overcome the limitations of the conventional decoupling capacitor solutions such as expensive on-chip NMOS capacitor and package-level discrete decoupling capacitor with narrow-band. The key idea of the proposed TSV-based DCSC is mounting the decoupling capacitors such as silicon-based NMOS capacitor and discrete capacitor on the backside of a chip and connecting the capacitors to the on-chip PDN through TSVs. Therefore, the TSV-based DCSC provides the lowest parasitic inductance (ESL: under several tens pH) through a short interconnections between the on-chip PDN and decoupling capacitors as well as the largest capacitance (up to several uF) by stacking the additional decoupling capacitors to 3D-IC systems.

This paper presents an optimized Waveform Relaxation solver for electrically-long high-speed channels terminated by nonlinear networks. The time-domain scattering operators of channel and terminations are cast as recursive convolutions and nonlinear discrete-time filters, respectively. A transverse and longitudinal decoupling is then applied to the channel operator, with the introduction of suitable relaxation sources, and solved iteratively until convergence. A frequency-dependent over-relaxation parameter is introduced in order to optimize the convergence rate. Numerical results show significantly reduced runtime and iteration count for critical benchmarks with respect to previous Waveform Relaxation formulations.

Accurate modeling of parameterized microwave and RF components often requires a large number of full-wave electromagnetic simulations. In order to reduce the overall simulation cost, a sequential sampling algorithm is proposed that selects a sparse set of data samples which characterize the overall response of the system. The resulting data samples can be fed into existing modeling techniques. The effectiveness of the approach is illustrated by a parameterized H-shaped microwave antenna.
