Abstract:
1. A double-sampling sigma-delta modulator circuit, the circuit comprising: an amplifier including an integrating capacitor; a switched capacitor conversion element including a single capacitor bank, wherein the single capacitor bank includes a first capacitive element and a second capacitive element; and a control element, wherein the control element provides phase signaling that identifies at least a first phase and a second phase; wherein during the first phase charge present on the single capacitor bank is transferred to the integrating capacitor, and the single capacitor bank is charged; and wherein during the second phase charge present on the single capacitor bank is transferred to the integrating capacitor, and the single capacitor bank is discharged by electrically coupling a first plate of the first capacitive element to a first plate of the second capacitive element and electrically coupling a second plate of the first capacitive element and a second plate of the second capacitive element to the integrating capacitor.
