In this paper, the eigenvalue problem with multiple uncertain parameters is analyzed by the sparse grid stochastic collocation method. This method provides an interpolation approach to approximate eigenvalues and eigenvectors’ functional dependencies on uncertain parameters. This method repetitively evaluates the deterministic solutions at the pre-selected nodal set to construct a high-dimensional...
A monotonic and low-power digitally controlled oscillator (DCO) with a cell-based design for system-on-chip applications is presented. The proposed monotonic DCO not only can achieve high delay resolution and wide operation range at the same time, but also maintain the delay monotonicity. Moreover, based on the proposed varactor-interpolator fine-tuning stage, the proposed DCO can provide monotonic...
