Patent number: 11095425Abstract: Methods, apparatus, and systems for communication over a multi-wire, multi-phase interface are disclosed. A clock recovery method includes generating a combination signal that includes transition pulses, each transition pulse being generated responsive to a transition in a difference signal representative of a difference in signaling state of a pair of wires in a three-wire bus. The combination signal is provided to a logic circuit that is configured to provide a clock signal as its output, where pulses in the combination signal cause the clock signal to be driven to a first state. The logic circuit receives a reset signal that is derived from the clock signal by delaying transitions to the first state while passing transitions from the first state without added delay. The clock signal is driven from the first state after passing a transition of the clock signal to the first state.Type: GrantFiled: August 25, 2020Date of Patent: August 17, 2021Assignee: QUALCOMM INCORPORATEDInventors: Ying Duan, Jing Wu, Shih-Wei Chou

Patent number: 11018719Abstract: A broadband, dual-polarized, cavity-backed slot antenna (CBSA) array is presented for enabling full-duplex wireless communication. The antenna consists of a thin rectangular cavity appropriately loaded with metallic septa to excite multiple resonances of similar desired field distribution to achieve consistent radiation characteristics over a wide bandwidth. Four pairs of orthogonal radiating slots are cut out on one of the broad-walls of the cavity; all of which are fed by two orthogonal slots on the opposite broad-wall of the cavity. The cavity is fed by an end-launch coaxial-to-waveguide transition to excite one of the channels. The other channel is excited by a two-pronged microstrip line symmetrically crossing over the other cavity feeding slot. Due to the out-of-phase coupling from the two prongs of the microstrip line to the other port, this type of excitation is shown to provide an unpredicted level of isolation between the two channels over a wide bandwidth.Type: GrantFiled: May 17, 2020Date of Patent: May 25, 2021Assignee: THE REGENTS OF THE UNIVERSITY OF MICHIGANInventors: Kamal Sarabandi, Seyed M.

Patent number: 11018907Abstract: In a PAM-N receiver, sampler reference levels, DC offset and AFE gain may be jointly adapted to achieve optimal or near-optimal boundaries for the symbol decisions of the PAM-N signal. For reference level adaptation, the hamming distances between two consecutive data samples and their in-between edge sample are evaluated. Reference levels for symbol decisions are adjusted accordingly such that on a data transition, an edge sample has on average, equal hamming distance to its adjacent data samples. DC offset may be compensated to ensure detectable data transitions for reference level adaptation. AFE gains may be jointly adapted with sampler reference levels such that the difference between a reference level and a pre-determined target voltage is minimized.Type: GrantFiled: June 11, 2020Date of Patent: May 25, 2021Assignee: Rambus Inc.Inventor: Nanyan Wang
