Title:
半導体装置
Document Type and Number:
Japanese Patent JP5714973
Kind Code:
B2
Abstract:
A pulse converter circuit includes a logic circuit to which a first signal is input and from which a second signal is output. The logic circuit includes a p-channel transistor which determines whether a voltage of the second signal is set to a first voltage depending on a voltage of the gate; and an n-channel transistor which determines whether the voltage of the second signal is set to a second voltage, which is higher than the first voltage, depending on a voltage of the gate. The p-channel transistor includes a semiconductor layer containing an element of a group 14. The n-channel transistor includes an oxide semiconductor layer.
