Abstract:
1. A phase interpolator comprising: a first circuit node for receiving a first signal having a first phase component; a second circuit node for receiving a second signal having a second phase component; a first capacitor having a first terminal and a second terminal, the first terminal of the first capacitor switchably coupled with the first circuit node; a second capacitor having a first terminal and a second terminal, the first terminal of the second capacitor switchably coupled with the second circuit node; a third circuit node coupled with the second terminal of the first capacitor and the second terminal of the second capacitor, the third circuit node configured to receive a third signal having a third phase component inclusively between the first phase component and the second phase component; and an inductor coupled with the third circuit node, the inductor configured to boost a voltage of the third signal.
