PROBLEM TO BE SOLVED: To provide segmented circuit in which noise shaping is improved. SOLUTION: The segmented circuit comprises a plurality of circuit segments, each having a first analog quantity defining means 10, 20 which defines a first analog quantity I for its segment, and also having a second analog quantity defining means 15, 25 which defines a second analog quantity I<SB>test</SB>for its segment, the second analog quantity for its segment distinctly less than the first analog quantity, an analog quantity selecting means SW1-SW4 for selecting the first analog quantity or the second analog quantity and a combination means which works so as to produce a combined analog quantity based on the respective selected analog quantities of a combination of the circuit segments.
