This paper presents a DFT/BIST technique for switched-capacitor (SC) circuits that consists of measuring all capacitance ratios of transfer functions in the DC domain. Then, the specifications of a SC circuit are computed from these measured capacitance ratios and compared to the fault-free ones. Moreover, a maximal fault diagnosis is realized for the capacitances. This test technique uses re-configur
