Abstract:
1. A resonator comprising: an operational amplifier having an input terminal and an output terminal; a first resistive element coupled between a first node and the input terminal of the operational amplifier; a second resistive element coupled between the first node and the output terminal of the operational amplifier; a first capacitive element coupled between a second node and the input terminal of the operational amplifier; a second capacitive element coupled between the second node and the output terminal of the operational amplifier; a third capacitive element coupled to the first node; a third resistive element coupled to the second node; a fourth resistive element coupled between the first node and a signal input terminal; a fourth capacitive element coupled between the second node and the signal input terminal; a fifth capacitive element coupled between the first node and the signal input terminal; and a sixth capacitive element coupled to the second node.
