  • Patent number: 10714163
    Abstract: An integrated circuit is operable to communicate with an external component. The integrated circuit may include driver circuits for outputting clock signals and associated control signals to the external component in accordance with a predetermined interface protocol. The clock signals may toggle more frequently than the associated control signals. To help mitigate potential transistor aging effects that could negatively impact timing margins for the control signals, the control signals may be periodically toggled even during idle periods as allowed by the predetermined interface protocol to help improve timing margins.

  • Patent number: 10223483
    Abstract: A methodology for defining resistance-capacitance (RC) design targets based on radio-frequency (RF) simulation is provided. In particular, the method may involve first determining capacitance targets and then determining resistance targets. To compute the capacitance targets, integrate circuit design and simulations tools may run transient analysis to identify critical nodes, perform small signal and sensitivity analysis for the capacitance on the critical nodes, revise original RF specifications by allocating additional margin, and perform interpolation among multiple capacitance values to obtain capacitive design targets that meet the revised specifications.

  • Patent number: 10200046
    Abstract: A delay-locked loop includes multiple inverters coupled together, wherein the inverters receive an input clock signal and output a first clock signal and a second clock signal. The input clock signal passes through a first set of inverters having a first number of inverters to generate the first clock signal. The input clock signal also passes through a second set of inverters having a second number of inverters one inverter greater than the first number of inverters to generate the second clock signal.
