Matthew Guthaus, Xuchu Hu: Distributed resonant clock grid synthesis. The Regents of the University of California, Adam Warwick Bell, Matthew Rupert Kaser, May 6, 2014: US08719748 (2 worldwide citation)

A method of implementing a VLSI clock network is implemented. That method includes a step of generating an initial VLSI clock grid for incorporation on a silicon die. An input grid buffer is then sized and implemented for the VLSI clock grid. LC tanks are then placed and sized in the VLSI clock grid ...

Matthew Guthaus: Distributed LC resonant tanks clock tree synthesis. THE REGENTS OF THE UNIVERSITY OF CALIFORNIA, Venable, Henry J Daley, Ryan T Ward, September 11, 2018: US10073937

A technique for implementing a clock tree distribution network having a clock buffer and a plurality of LC tanks that each take into \consideration local capacitance distributions and conductor resistances. An AC-based sizing formulation is applied to the buffer and to the LC tanks so as to reduce t ...
