Abstract
A level shift circuit shifts a first voltage level to a second voltage level that is different from the first voltage level. The level shift circuit includes a set-level circuit 21 configured to detect and transmit a set signal that is used to set a logic voltage state based on the second voltage level, a reset-level circuit 22 configured to detect and transmit a reset signal that is used to reset the logic voltage state based on the second voltage level, and a reference-level circuit C3 configured to provide a reference signal that is used to detect the set signal and reset signal based on the second voltage level. The set-level circuit, reset-level circuit, and reference-level circuit transmit signals from the first voltage level to the second voltage level through capacitors C1, C2, and C3, respectively.
