Abstract
Methods for creating a tunable phase shifter include setting physical dimension limits for the tunable phase shifter; determining electrical parameters for the tunable phase shifter, including a characteristic impedance limit and a maximum inductance tuning range, based on the physical dimension limits using a processor; and determining physical dimensions for an inductance tuning transistor and a capacitor tuning transistor, such that a characteristic impedance range is minimized.
