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.
Claims14
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;
- 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, wherein the clamp inverter includes at least a first Zener diode coupled to the output of the second inverter;
- and
- a temperature compensator configured to compensate for variations in the clamping voltage caused by a temperature change, wherein the temperature compensator is coupled to an anode of the first Zener diode and has a polarity opposite to a temperature coefficient of the first Zener diode according to a temperature rise.
