Abstract
A method of increasing a current flowing through an inductor includes receiving an input signal with a driver stage, the driver stage including the inductor coupled in series with a loading between an output node of the driver stage and a power line. In response to a transition in the input signal from a first voltage state to a second voltage state, a first current flowing through the loading and the inductor is increased. During the transition in the input signal, the current flowing through the inductor is increased by increasing a second current in a circuitry though a node between the inductor and the loading.

A method of increasing a current flowing through an inductor, the method comprising:
- receiving an input signal with a driver stage, the driver stage comprising the inductor coupled in series with a loading between an output node of the driver stage and a power line;
- and
- in response to a transition in the input signal from a first voltage state to a second voltage state, increasing a first current flowing through the loading and the inductor;
- and
- during the transition in the input signal, increasing the current flowing through the inductor by increasing a second current in a circuitry though a node between the inductor and the loading.
A method of increasing a current flowing through an inductor, the method comprising:
- receiving an input signal with a first pre-driver stage at a first input node of the first pre-driver stage;
- generating a pre-driver signal with the first pre-driver stage based on the input signal;
- receiving the pre-driver signal with a driver stage, the driver stage comprising the inductor coupled in series with a loading between an output node of the driver stage and a power line;
- and
- in response to a transition in the input signal from a first voltage state to a second voltage state, increasing the current flowing through the inductor by
- increasing a first current flowing through the loading, and
