摘要：
A resonator circuit enabling temperature compensation includes an inductor coupled between a first node and a second node of the resonator circuit; a capacitor circuit coupled between the first node and the second node; and a temperature compensation circuit coupled between the first node and the second node. The temperature compensation circuit comprises a varactor coupled to receive a temperature control signal that sets the capacitance of the varactor. A method of generating a resonating output is also disclosed.
