Electronic circuit including pipeline converting circuit

An electronic circuit comprising:

• a first converting circuit configured to output a first residual voltage associated with converting an analog signal into a first digital signal and to output a second residual voltage generated as energy stored in a first capacitive element varies based on the first residual voltage;
• and
• a second converting circuit configured to perform an interpolation operation based on a third residual voltage and a fourth residual voltage and to output a second digital signal associated with the analog signal,
• wherein the third residual voltage and the fourth residual voltage are obtained by respectively amplifying the first residual voltage and the second residual voltage through one amplifying path.

An electronic circuit comprising:

• a first converting circuit configured to output a first residual voltage generated as an analog signal is converted into first bits of a first digital signal and a second residual voltage generated based on the first residual voltage;
• an amplifying circuit configured to generate a third residual voltage by amplifying the first residual voltage through an amplifying path and to generate a fourth residual voltage by amplifying the second residual voltage through the amplifying path;
• and
• a second converting circuit configured to generate second bits of the first digital signal, based on energy stored in first capacitive elements based on the third residual voltage and energy stored in second capacitive elements based on the fourth residual voltage.
