Abstract

A technique for tuning a ladder-shaped inductor that achieves a finer tuning resolution by severing one or more shorts, skipping the severing of one or more shorts, and severing one or more subsequent shorts within the ladder-shaped inductor. This technique can be applied to a voltage-controlled oscillator using a differential or single-ended ladder-shaped inductor as part of the resonant circuit. Within an oscillator, such a technique provides for a more precise modulation of the effective inductance of the ladder-shaped inductor, which enables an improved tuning resolution of the operating frequency of the oscillator.
