CIRCUIT DEVICE AND ELECTRONIC APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a circuit device capable of reducing an effect on a circuit operation due to fluctuations of a substrate potential, an electronic apparatus and the like.SOLUTION: A circuit device includes: a first circuit which comprises a transistor with a DMOS structure formed on a first N-type buried layer 51 on a P-type substrate 41 and is formed in a first region 10; and a second circuit which comprises a transistor with a CMOS structure formed on a second N-type buried layer 52 separated from the first N-type buried layer 51 and is formed in a second region 20.
