Publication number: 20140198550Abstract: An apparatus is provided. A differential pair of transistors is configured to receive a first differential signal having a first frequency, and a transformer, having a primary side and a secondary side is provided. The primary side of the transformer is coupled to the differential pair of transistors, and the secondary side of the transformer is configured to output a second differential signal having a second frequency, where the second frequency is greater than the first frequency. A first transistor is coupled to the first supply rail, the primary side of the transformer, and the differential pair of transistors, where the first transistor is of a first conduction type. A second transistor is coupled to the second supply rail, the primary side of the transformer, and the differential pair of transistors, where the second transistor is of a second conduction type.Type: ApplicationFiled: January 14, 2013Publication date: July 17, 2014Applicant: Texas Instruments IncorporatedInventors: Swaminathan Sankaran, Vijaya B.

Patent number: 7764210Abstract: A video driver includes a current-to-voltage converter circuit that converts an analog input current to a corresponding analog voltage. Active termination circuitry is configured to synthesize an output impedance at an output thereof that substantially matches a load impedance to which the output is coupled, the active termination circuitry buffering the analog voltage to the output.Type: GrantFiled: December 20, 2006Date of Patent: July 27, 2010Assignee: Texas Instruments IncorporatedInventors: Vijaya B.

Patent number: 7586357Abstract: A system for providing a desired substantially constant resistance includes a first transistor interconnected between a first node and a second node. The system also includes a second transistor, the second transistor being diode connected, the first transistor and the second transistor forming a current mirror. A voltage divider is coupled to provide a portion of a voltage associated with the first transistor to the second transistor, the voltage divider being configured parallel to the first transistor to provide a substantially constant resistance between the first node and the second node. A current source is coupled to the second transistor, the current source being controlled to draw an amount of current through the second transistor to set the substantially constant resistance substantially equal to the desired substantially constant resistance.Type: GrantFiled: January 12, 2007Date of Patent: September 8, 2009Assignee: Texas Instruments IncorporatedInventors: Vijaya B. Rentala, Baher Haroun

Patent number: 7129875Abstract: An analog-to-digital (A/D) converter system is provided that compensates for operating variations associated with one or more passive components of the A/D converter. In one aspect of the present invention, the A/D converter system comprises a sigma delta modulator having at least one passive component and a feedback path that includes at least one switched digital-to-analog converter (DAC), and a tracking reference generator that provides compensated reference signals to the at least one switched DAC for providing feedback to the sigma delta modulator. The compensated reference signals include inverse variations that cancel operating variations associated with the at least one passive component.Type: GrantFiled: July 8, 2005Date of Patent: October 31, 2006Assignee: Texas Instruments IncorporatedInventors: Oguz Altun, Vijaya B.
