Latest Patent Applications

Carroll's latest patent application is titled "Techniques for Receiver Non-Linearity Calibration." This application describes various techniques for correcting distortion in an analog input signal after digitization in a receiver signal chain. The techniques include a system that stores concatenated distortion correction terms, allowing for efficient data handling and processing. Additionally, the system features a smaller number of replica memories compared to primary memories, which store operational data. The replica memories are updated with new data and can be swapped with primary memories to update them without interrupting system operations. Furthermore, the techniques include a dither system that uses two memories to store and process the dithered signals, which are then combined to produce a noise-corrected digital output. The techniques also encompass a system to correct distortions in analog input signals processed through multiple parallel paths.

Conclusion

Carroll C Speir is a notable figure in the realm of innovations related to receiver non-linearity calibration, showcasing his expertise through his latest patent applications. His work at Analog Devices, Inc. reflects his commitment to advancing technology in signal processing.
