A blind source separation (BSS) is proposed to reject the crosstalk between inductive-coupling channels in 3-D systems. The phase and permutation ambiguities inherent to BSS are compensated for in the proposed technique. A continuous-time natural gradient BSS with integrator output swing bounding, which is amenable for high-speed implementation, is also proposed. Techniques to reduce the implement...

| | PDF (674 KB) | HTML

A digital-to-time converter (DTC) produces a time delay based on a digital code. Similar to data converters, linearity is a key metric for a DTC and it can be characterized by its integral nonlinearity (INL). However, measuring the INL of a subpicosecond-resolution DTC is problematic, even when using the best available high-speed oscilloscopes. In this brief we propose a new method to measure the ...
