Abstract: A multilingual synthesizer synthesizes speech, for any given monolingual or mixed-language text, that is intelligible to human listeners. The necessity for such synthesizer arises in a country like India, where multiple languages coexist. For the…

Abstract: Optical-frequency synthesizers, which generate frequency-stable light from a single microwave-frequency reference, are revolutionizing ultrafast science and metrology, but their size, power requirement and cost need to be reduced if they are to be more widely…

Abstract: This letter presents a fractional-N frequency synthesizer with an ultrawideband continuously tuning range of 32.4% centered at 26.85- and 8.7-GHz chirp for frequency-modulated continuous-wave (FMCW) radars. The synthesizer uses a fractional-N 9-GHz charge-pump phase-locked loop…

Abstract: Programmable and on-demand generation of photonic entanglement is enabled by a dynamically controlled loop-based circuit. Quantum information protocols require various types of entanglement, such as Einstein-Podolsky-Rosen, Greenberger-Horne-Zeilinger, and cluster states. In optics, on-demand preparation of…
