  • Publication number: 20250247054
    Abstract: A load inductor has first and second nodes. The first node couples to a first terminal of a first switch. A second terminal of the first switch couples to an output of a first low noise amplifier (LNA). The second node couples to a third terminal of a second switch. A fourth terminal of the second switch couples to an output of a second LNA. In response to receiving a single-ended signal at the first LNA, the first LNA is turned on, the first switch is closed, the second LNA is turned off, and the second switch is opened. In response to receiving the signal at the second LNA input, the first LNA is turned off, the first switch is opened, the second LNA is turned on, and the second switch is closed. The signal is transformed to a differential signal across the first and second inductor nodes.
