Various circuits, systems and methods are disclosed for providing double-sampling sigma-delta modulator circuits. For example, circuits are disclosed that include an amplifier with an integrating capacitor, a switched capacitor conversion element that includes a single capacitor bank, and a control element that provides phase signaling that identifies at least two phases. In operation, charge present on the single capacitor bank is transferred to the integrating capacitor and the single capacitor bank is charged during one phase. During the other phase, charge present on the single capacitor bank is transferred to the integrating capacitor, and the single capacitor bank is discharged.
