Latest Patents

One of Geir Ostrem's latest patents is titled "Digital technique for excess loop delay compensation in a continuous-time delta sigma modulator." This invention involves a continuous-time delta sigma modulator that includes a quantizer, a buffer module, and a reference module. The quantizer features a comparator that updates a digital output each cycle of a clock signal based on a comparison of a reference potential with an input generated from an analog signal sample. The buffer module stores the digital output for a predetermined delay period and outputs it as a delayed digital output. The reference module selectively varies the reference potential based on this delayed digital output. Another patent under his name also focuses on a similar digital technique for excess loop delay compensation, emphasizing the importance of the quantizer and reference module in generating accurate digital outputs.
