Title:
FREQUENCY DIVIDING CIRCUIT, AND SEMICONDUCTOR DEVICE INCLUDING THE SAME
Document Type and Number:
Japanese Patent JP2013009368
Kind Code:
A
Abstract:
To provide a semiconductor device with lower power consumption and smaller occupied area.
As a transistor included in a flip-flop circuit, a transistor having a channel formed in an oxide semiconductor is used. Thus, a frequency dividing circuit with fewer transistors, lower power consumption, and smaller occupied area can be achieved. Moreover, the use of the frequency dividing circuit can achieve a semiconductor device with stable operation and high reliability.
