We develop a non-quasi-static MOSFET compact model suitable for simulating RF circuits operating under GHz frequency. The model takes into account the carrier dynamics by incorporating the time delay for the carriers to form a channel. Both the time-domain and frequency-domain expressions are...

What market (spot or future) reflects news first? This question is investigated with Granger causality and Breitung and Candelon (2006) causality test in the frequency domain for Brazilian stock market. The results differ depending on which index (ETF, exchange traded funds, or the spot index)...

We study the fitting of time series models via the minimization of a multi-step-ahead forecast error criterion that is based on the asymptotic average of squared forecast errors. Our objective function uses frequency domain concepts, but is formulated in the time domain, and allows the...

The paper considers parameter identification, estimation and inference in medium scale DSGE models from a frequency domain perspective using the framework developed in Qu and Tkachenko (2010). The analysis uses Smets and Wouters (2007) as an illustrative example, motivated by the fact that it...

This paper considers inference and model diagnostics for log-linearized DSGE models allow- ing an unknown subset of parameters to be weakly (including un-) identified. The framework allows for latent state variables, measurement errors and also permits analysis using only part of the spectrum,...

This paper applies several causality tests to analyze whether sunspot numbers (used as an approximate proxy for the solar activity) cause global temperatures, using monthly data covering the time period 1880:1-2013:9. Both parametric and non-parametric causality tests are performed, which...

Purpose – The purpose of this study is to attempt to analyze Granger causality in the frequency domain framework between producers' prices measured by wholesale price index (WPI) and consumers' prices measured by consumer price index (CPI) in the context of India. Design/methodology/approach...

This paper investigates the predictive power for the future domestic economic activity included in the domestic stock prices, using a Granger causality analysis in the frequency domain. We are able to evaluate whether the predictive power is concentrated at the slowly fluctuating components or...

We exploit dynamic correlations to estimate determinants of output comovement between OECD countries. Trade intensity, financial integration, and specialization patterns have significantly different effects on comovements at different frequencies. This sheds more light on previous results based...

To assess the variability of heart rate in the frequency domain, usually the spectral density function of the tachogram series is estimated. However, classical spectral density estimates are well known to be prone to outlying observations; hence, robustness is an issue. Therefore, the heart rate...
