Publication number: 20150234968Abstract: A list of input registers and output registers for a circuit design are provided. The circuit design is modified by traversing output connections paths for each input register and replacing any register in the output connection paths with a wire unless the register is a listed output register. An initial total cycle time value for the modified circuit design is determined. A gate level description for the modified circuit design is obtained by a macro synthesis with the initial total cycle time value. The total cycle time value for the modified circuit design is then varied in order to determine the theoretical limit of the modified circuit design. This theoretical limit is realized when negative slacks are present in a macro synthesis of the modified circuit design for a given total cycle time value. Based on this theoretical limit, the minimum pipeline depth of the circuit design is determined.Type: ApplicationFiled: January 23, 2015Publication date: August 20, 2015Inventors: Maarten J. Boersma, Thomas Fuchs, David Lang, Friedrich Schroeder

Patent number: 7652464Abstract: An RF power detector having a wide dynamic range may comprise a chopping amplifier and is configured to detect pulsed high frequency RF signals. The chopping amplifier controlled by a bias current regulator amplifies and chops an RF signal by periodically enabling and disabling the amplifier according to a system clock. The chopped high frequency RF signal feeds a Schottky diode biased to operate in the square law region for weak signals. The Schottky diode voltage is tapped and high pass filtered. The voltage drives a logarithmic and linear converter. The converter outputs are summed to produce an output voltage that is a repeatable and stable monotonically increasing function of the RF power.Type: GrantFiled: May 4, 2007Date of Patent: January 26, 2010Assignee: ViaSat, Inc.Inventors: David Lang, Noel Lopez
