Reservoir Delineation Using Bandwidth Extension and Phase Decomposition
… original seismic data and derived attributes. Bandwidth extension using sparse-layer inversion better resolves thin layers than does the original seismic data and can detect multiple interfaces that are not otherwise seismically separated. As the hydrocarbon-filled reservoirs are low impedance …

Operational Amplifier Bandwidth Extension Using Negative Capacitance Generation
A need for high bandwidth operational amplifiers, or op-amps, exists for certain applications. This need requires research in the area of op-amp bandwidth extension. The proposed method of this thesis uses Negative Capacitance Generation (NCG), which involves using the Miller effect to generate an …

An Application of Spectral Translation and Spectral Envelope Extrapolation for High-frequency Bandwidth Extension of Generic Audio Signals
… yet effective algorithm for blind high-frequency bandwidth extension of audio signals, a means of improving perceptual quality for sound which has been previously low-pass filtered or downsampled (typically due to storage considerations). The algorithm combines an application of the modulation …

Analysis and Optimisation of an Organic Optical Link
… a novel electrical model is built to predict bandwidth. Extension of the OLED physical simulation shows for the first time that by using a constant fraction of the overall simulated device resistance (a ‘luminescent resistance’), this RC-based model can be used to predict device small signal …

Clock multiplication techniques for high-speed I/Os
… PLLs. The proposed HPC-PI alleviates the bandwidth trade-off between VCO phase noise suppression and ΔΣ quantization noise suppression. By combining the phase detection and interpolation functions into an XOR phase detector/interpolator (XOR PD-PI) block, accurate quantization error …
