Patent abstract
In one embodiment, an integrated phase shifter includes: a plurality of stages, wherein each stage comprises: a transistor amplifier configured to amplify a voltage signal received at an input node into an amplified voltage signal at an output node according to a gain, wherein the transistor amplifier is configured such that the gain is proportional to a bias signal; an integrated inductor loading the output node, wherein the gain of the transistor amplifier is also proportional to an inductance of the integrated inductor; and a varactor diode loading the output node, wherein the varactor diode has a variable capacitance responsive to a control voltage.
