Patent number: 11936504Abstract: A decision feedback equalizer includes a summer, a slicer, and a feedback circuit. The summer is configured to receive an input signal and a correction signal from the feedback circuit and generate a summer output signal. The slicer includes a first slicer and a second slicer, both are configured to receive the summer output signal as an input, and output a slicer output signal. The feedback circuit is configured to receive the slicer output signal, and based on the slicer output signal, generate the correction signal. The input signal is received at a first clock rate. The first slicer and the second slicer sample the input signal at a second clock rate, about half the first clock rate.Type: GrantFiled: May 31, 2022Date of Patent: March 19, 2024Assignee: Ceremorphic, Inc.Inventors: Ajay Mantha, Poorna Chandrika Kondeti

Patent number: 11916679Abstract: A bitstream modifier is operative on a packet which uses repetition coding. The bitstream modifier increases randomness of the data in a deterministic manner such that spectral spurs from repetition coding are greatly reduced, thereby providing greater available transmit power. In another example of the invention, baseband samples of a header and/or payload for a Bluetooth packet are modified by a canonical sequence with a low slew rate for data such that the variations in frequency may be tracked by a receiver and the transmitted spectral spurs reduced.Type: GrantFiled: August 28, 2020Date of Patent: February 27, 2024Assignee: Silicon Laboratories Inc.Inventors: Sriram Mudulodu, Divyaxi Rudani, Manoj Medam, Partha Sarathy Murali, Ajay Mantha, Suchin Gupta
