摘要： Described is an apparatus which comprises: a low-side switch coupled to an output node for providing regulated voltage supply; and a first driver operable to cause the low-side switch to turn off when the output node rises above a first transistor threshold voltage. Described is also a voltage regulator which comprises: a signal generator to generate a pulse-width modulated (PWM) signal; a bridge having a low-side switch coupled to an output node for providing regulated voltage supply according to the PWM signal; a first driver operable to cause the low-side switch to turn off when the output node rises above a first transistor threshold voltage; and a bridge controller to provide control signals to the first driver. The voltage regulator may operate without diode clamps and its operation is self-timed. The voltage regulator also provides tolerance against process variation.

摘要： A transformer integrated on a die, the transformer comprising a set of conductive lines formed on the die within one layer and interconnected among each other so that no two lines belonging to any one winding are nearest neighbors. The set of conductive lines is surrounded by a magnetic material, which may be amorphous CoZrTa, CoFeHfO, CoAlO, FeSiO, CoFeAlO, CoNbTa, CoZr, and other amorphous cobalt alloys. The transformer may be operated at frequencies higher than 10 MHz and as high as 1 GHz, with relatively low resistance and relatively high magnetic coupling between the windings.
