ALEXANDRIA, Va., Oct. 21 -- United States Patent no. 12,445,144, issued on Oct. 14, was assigned to Analog Devices International UnLtd. Co. (Limerick, Ireland).
"Continuous-time ADC calibration techniques" was invented by Asha Ganesan (Markham, Canada), Donald W. Paterson (Winchester, Mass.), Sharvil Pradeep Patil (Toronto) and Nevena Rakuljic (Del Mar, Calif.).
According to the abstract* released by the U.S. Patent & Trademark Office: "CT ADCs based on continuous-time residue generation systems require accurate estimation of analog transfer functions. This is done by using a pseudo random bit sequence, injected using a DAC, that traverses the transfer function to be measured. Mismatch in the injection DAC introduces errors in the transfe...
