Abstract: Techniques for denoising an electromagnetic signal are disclosed. The techniques utilize an antenna, a weight adaptation component, a reservoir computer including a computer interpretable neural network, a delay embedding component, and an output layer computer. The techniques include passively acquiring an electromagnetic signal by the antenna, producing a plurality of reservoir state values by the reservoir computer based on the electromagnetic signal, collecting the plurality of reservoir state values by the delay embedding component into a historical record, determining a plurality of reservoir state value weights by the weight adaptation component based at least in part of the historical record, scaling, by the plurality of reservoir state value weights, to produce a plurality of output values, the plurality of reservoir state values by the output layer computer, and outputting the plurality of output values, where the scaling occurs over a plurality of clock cycles of a clock for the system.

Abstract: A comb enhanced oscillator in which a drive signal from a first oscillator is split into two signals. The first signal is applied to a nonlinear resonator producing a phononic frequency comb of equally spaced resonances. The second signal is passed through an amplitude detector and a phase shifter. In one embodiment, the comb is applied to the phase shifter to correct for AM-PM cross-correlation noise and then applied to a phase lock loop (PLL) for locking to a second oscillator. The output of the second oscillator is used as the output of the comb enhanced oscillator.

Abstract: A voltage controlled oscillator (VCO) which can be configured with a smaller tuning range than is ordinarily required is presented. Ordinarily, the tuning range is selected much broader than the application warrants so that sufficient range is still provided despite VCO process variations. The inventive VCO is able to substantially eliminate the effects of process variation by utilizing a calibration circuit and process, so that variation in VCO device operation is minimized despite substantial process variation. Accordingly, the inventive VCO device is subject to reduced levels of jitter as its range need not be utilized for overcoming process variation arising during device fabrication.
