Abstract
Disclosed herein are devices, systems, and methods for improved demodulation. In one embodiment, a demodulator includes an input port configured to receive an analog input signal having a first frequency spectrum, a delta-sigma modulator electrically coupled with the input port, a digital downconverter electrically coupled with the delta-sigma modulator, and a filter electrically coupled with the digital downconverter. The filter is configured for a passband having a second frequency spectrum. The demodulator also includes an output port electrically coupled with the filter. The output port is configured to provide an output signal having the second frequency spectrum.
