  • Pulse generator and driving circuit comprising the same
    Patent number: 9755625
    Abstract: A pulse generator includes a first inverter configured to inverse an input pulse and output a result, a second inverter configured to inverse the output of the first inverter and output a result, a clamp inverter configured to generate a clamping voltage by clamping the output of the second inverter and generate an output pulse through a source follower which operates according to the clamping voltage, and a temperature compensator configured to compensate for variations in the clamping voltage caused by temperature change.
    Type: Grant
