Signal converting system having level converter for use in high speed semiconductor device and method therefor

A level converter comprising:

• a converting part having a pre-charge node and a reset node to output through the pre-charge node a level-converting signal having a different level from a level of an input signal in response to the input signal;
• a delay part for delaying the level-converted signal of the converting part by a predetermined time;
• and
• a self-reset part for generating a reset signal in response to the delayed level-converted signal of the delay part to output it to the reset node of the converting part so that a pulse width of the level-converted signal as output is set as much as the sum of the predetermined delay time and an internal operation delay time and the pre-charge node is pre-charged.

A level converter comprising:

• a converting part having a pre-charge node and a reset node to output through an output node a level-converting signal having a different level from a level of an input signal in response to the input signal;
• a delay part for receiving through the output node and delaying the level-converted signal of the converting part by a predetermined time;
• and
• a self-reset part for generating a reset signal in response to the delayed level-converted signal of the delay part to output it to the reset node of the converting part so that a pulse width of the level-converted signal as being output through the output node is set as much as the sum of the predetermined delay time and an internal operation delay time and the pre-charge node is pre-charged.

A level-converting method comprises the steps of:

• outputting a level-converted signal having a different level from that of an input signal in response to shift of an input signal;
• delaying the level-converted signal by a predetermined delay time;
• and
• generating a reset signal in response to the delayed level-converted signal and controlling the level-converted signal by the reset signal so that a pulse width of the level-converted signal as output is set as much as the sum of the predetermined delay time and an internal operational delay time.
