Patent number: 9973329Abstract: When a data path includes CMOS circuitry, such circuitry may introduce jitter into the data signal. Embodiments are described in which additional data transitions are made to occur, and these additional data transitions may change the characteristics of the data frequency content transferred to the power supply so that such noise may be better filtered. This may have an effect of reducing jitter in the data signal. In one embodiment, a second data signal is generated to be a version of a first data signal with every second bit inverted. Second CMOS circuitry receives the second data signal in parallel to first CMOS circuitry receiving the first data signal. The first CMOS circuitry and the second CMOS circuitry are connected to a same power supply.Type: GrantFiled: March 30, 2017Date of Patent: May 15, 2018Assignee: INPHI CORPORATIONInventors: Sheldon James Hood, Paul Thomas Banens

Patent number: 8126663Abstract: An electronic signal level detection system and method are provided. The method receives an analog input signal having a variable voltage and compares the input signal voltage to a threshold. A detection signal is generated for input signal voltages exceeding the threshold in a periodic first time frame. In a second periodic time frame (following the first time frame), a count is updated in response to the generated detection signals. The count is used to create a metric representative of the difference between the input signal voltage and the threshold. The count is incremented in response to the generating a detection signal (“1”) in the first time frame, and decremented in response to not generating a detection signal (“0”) in the first time frame.Type: GrantFiled: February 27, 2010Date of Patent: February 28, 2012Assignee: Applied Micro Circuits CorporationInventors: Matthew Douglas Brown, Sheldon James Hood, Guy Jacque Fortier, Stan Harry Blakey
