Patent ID: 7053732

Claim:
A method for adjusting a time-delay for a high radio frequency (RF) application on the order of around 1 GHz or more using a multi-bit time-delay adjuster unit, wherein the unit has a tunable time-delay within a specified time-delay interval [0,T], and is adapted to reach a desired time-delay, the method comprising: defining a total number of level divisions p, defining for each level division a time-delay segment ΔT(k), where k is an integer number from 1 to p, setting a control parameter Cp, where Cp is a measure of a relation between a present time-delay and the desired time-delay, determining a time-delay segment sum by adding time-delay segments ΔT(k), and repeating the setting step and the determining step until the desired time-delay is reached or the sum is within an allowed precision range Tp, and Cp is then given a predetermined value.
