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.
Claims23
A pulse generator, comprising:
- a first inverter configured to invert an input pulse and output a result;
- a second inverter configured to invert the output of the first inverter and output a result;
- and
- 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.
A driving circuit, comprising:
- a pulse generator comprising a first zener diode and a source follower, and being configured to clamp a signal corresponding to an input pulse through the first zener diode and generate a clamping voltage, wherein the source follower is configured to operate according to the clamping voltage to generate an output pulse;
- and
- a level shifter comprising a high voltage device coupled between a high voltage and a ground, wherein the high voltage device is configured to switch according to the output pulse to shift the level of the output pulse and output a result.
