Latest Patents
David Lamb holds a patent for "Circuits, systems, and methods for providing asynchronous sample rate conversion for an oversampling sigma delta analog to digital converter." This invention focuses on a variable output data rate converter circuit that meets performance requirements while maintaining low circuit complexity. The converter circuit includes an oversampling sigma delta modulator circuit that quantizes an analog input signal at an oversampled rate, outputting a sigma delta modulated signal. Additionally, it features a transposed polynomial decimator circuit that decimates the sigma delta modulated signal, producing a first decimated signal, and an integer decimator circuit that further decimates this signal by an integer factor to achieve a desired output data rate. The transposed polynomial decimator circuit incorporates a transposed polynomial filter circuit and a digital phase locked loop circuit, which tracks the ratio between the sampling rate of the first decimated signal and the oversampled rate, outputting an intersample position parameter to the transposed polynomial filter circuit.
