Title: Level conversion circuit
Inventor: RI EIKAN
IPC: H03K19/0185
Filed: 2003-04-03
Abstract: <P>PROBLEM TO BE SOLVED: To provide a level conversion circuit capable of increasing an operating speed without increasing the power consumption.  <P>SOLUTION: When an input signal Sin changes from a high level to a low level, the impedance of an n-type MOS transistor MN11 is decreased attended with increase in a current I3, and a voltage at an output node Nout is decreased. Further, since the impedance of a p-type MOS transistor MP 11 is changed from an ON state into an OFF state attended with an increase in a voltage at a node N2, the trailing speed of the voltage at the output node Nout is accelerated. When the input signal Sin changes from the low level to the high level, a current I8 increases in response to the increase in a current I6, while a p-type MOS transistor MP12 changes from ON to OFF, the voltage at the node N2 is decreased by the current I8. Thus, the rising speed of the voltage at the output node Nout is accelerated.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
