| 发明名称 | Continuous tunable LC resonator using a FET as a varactor | ||
| 摘要 | A varactor includes a field effect transistor (FET) integrated with at least a portion of a bipolar junction transistor (BJT), in which a back gate of the FET shares an electrical connection with a base of the BJT, and in which a reverse voltage applied to the back gate of the FET creates a continuously variable capacitance in a channel of the FET. | ||

| 主权项 | 1. A varactor, comprising: a bipolar junction transistor (BJT) including a base and an emitter; and a field effect transistor (FET) integrated with at least a portion of the BJT, in which a back gate of the FET shares an electrical connection with the base of the BJT, and in which a reverse voltage applied to the back gate of the FET creates a continuously variable capacitance in a channel of the FET formed at least partially in an emitter layer of the BJT. | ||
