  • Circuit for driving high-side transistor utilizing voltage boost circuits
    Patent number: 9065437
    Abstract: A circuit for driving a transistor includes a drive circuit, a first voltage boost circuit and a second voltage boost circuit. The drive circuit has a first specific node, a second specific node, and a third specific node coupled to a control node of the transistor. The drive circuit is arranged for coupling the first specific node to the third specific node according to at least a voltage of the first specific node and a voltage of the second specific node in order to charge the control node. The first voltage boost circuit is coupled between the first specific node and a connection node of the transistor, and is arranged for boosting the voltage of the first specific node. The second voltage boost circuit is coupled between the first specific node and the second specific node, and is arranged for boosting the voltage of the second specific node.

  • Circuitry with resistive input impedance for generating pulses from analog waveforms
    Patent number: 6486819
    Abstract: A decoder for generating output pulses or oscillations in response to input analog waveforms includes a circuit having a variable operating point and having a transfer function characterized by an unstable operating region bounded by a first stable operating region and a second stable operating region. In one embodiment, the circuit is characterized by having a resistive input impedance. The analog waveform forces the operating point of the circuit into its unstable and stable regions to produce oscillatory and non-oscillatory behavior at the circuit's output.
