  • High side boosted gate drive circuit
    Patent number: 7733135
    Abstract: A high-side boosted gate drive circuit is disclosed. In a particular example, an output driver is described, comprising a switching device configured to selectively conduct current in response to a charge being present at a control terminal for a duty cycle, a charging device configured to deliver charge to the control terminal based on the first duty cycle, a charge control device configured to selectively couple the charging device to deliver charge to the control terminal and to selectively decouple the charging device from the control terminal to charge the charging device, and a discharge control device configured to remove charge from the control terminal.
    Type: Grant
    Filed: August 13, 2008
    Date of Patent: June 8, 2010
    Assignee: Texas Instruments Incorporated

  • Modulation scheme for filterless switching amplifiers with reduced EMI
    Patent number: 6614297
    Abstract: A ternary modulation scheme for filterless switching amplifiers with reduced EMI reduces the common mode component of the signal by allowing only one state with zero differential voltage across the load to exist. The ternary modulation scheme is more efficient than the quaternary modulation scheme when applied to class-D filterless switching amplifiers since the gates of the power MOSFETs are being charged and discharged at only a small duty cycle instead of 50% duty cycle.
