Integrator, resonator, and oversampling A/D converter |
摘要 |
An integrator includes an operational amplifier, a first filter connected to an inverting input terminal of the operational amplifier, and a second filter connected between the inverting input terminal and an output terminal of the operational amplifier. The first filter includes n resistive elements connected in series, and (n−1) capacitive elements each having one end connected to an interconnecting node of the resistive elements and the other end connected to ground. The second filter includes n capacitive elements connected in series, and (n−1) resistive elements each having one end connected to an interconnecting node of the capacitive elements and the other end connected to ground. |
