Abstract
A phase interpolating (PI) system includes: a PI stage configured to receive first and second clock signals and a multi-bit weighting signal, and generate an interpolated clock signal; and an amplifying stage configured to receive and amplify the interpolated clock signal, the amplifying stage including a capacitive component. The capacitive component is tunable to exhibit non-zero capacitances. The capacitive component has a Miller effect configuration resulting in a reduced footprint of the amplifying stage.
