Semiconductor integrated circuit, electronic device, solid-state imaging apparatus, and imaging apparatus

摘要

A semiconductor integrated circuit includes a first semiconductor substrate in which a part of an analog circuit is formed between the analog circuit and a digital circuit which subjects an analog output signal output from the analog circuit to digital conversion; a second semiconductor substrate in which the remaining part of the analog circuit and the digital circuit are formed; and a substrate connection portion which connects the first and second semiconductor substrates to each other. The substrate connection portion transmits an analog signal which is generated by a part of the analog circuit of the first semiconductor substrate to the second semiconductor substrate.
