Abstract:
A voltage level converter circuit, comprising:an output node;a first node having a first voltage;a first transistor of a first conductivity type, connected between said output node and said first node, and turned on when an input voltage having a first logic level is supplied to a gate thereof;a second node having a second voltage;a second transistor of the first conductivity type connected between said output node and said second node, and turned on when said input voltage attains a second logic level;a third transistor of the first conductivity type connected between a gate of said second transistor and said second node;a fourth transistor of the first conductivity type connected between a gate of said third transistor and said second node, and having a gate connected to a gate of said second transistor;a fifth transistor of the first conductivity type connected between a gate of said first transistor and a drain of said fourth transistor, and having a gate. supplied with a control signal according to a level of a second voltage;a sixth transistor of a second conductivity type connected between a gate of said fifth transistor and a gate of said third transistor, and having a gate connected to a gate of said second transistor; anda seventh transistor of the second conductivity type connected between a gate of said fifth transistor and a gate of said fourth transistor, and having a gate connected to a gate of said third transistor.
