Electronic circuit including pipeline converting circuit

Abstract

An electronic circuit includes a first converting circuit, an amplifying circuit, and a second converting circuit. The first converting circuit outputs a first residual voltage associated with converting an analog signal into a first digital signal and a second residual voltage generated based on the first residual voltage. The amplifying circuit generates a third residual voltage by amplifying the first residual voltage through an amplifying path during a first time duration and generates a fourth residual voltage by amplifying the second residual voltage through the amplifying path during a second time duration after the first time duration. The second converting circuit generates a second digital signal associated with the analog signal by performing an interpolation operation based on the third residual voltage and the fourth residual voltage.
