摘要： In the present method of measuring the current of a first current source, the current thereof may be combined with either the current of a second current source, or the current of a third current source. Based on a combination of the current of the first current source and either (a) the current of the second current source or (b) the current of the third current source, a digital output is provided. If this digital output is of a first value, the state of combining the current of the first current source with the current of the second current source becomes in effect. If this digital output is of a second value, the state of combining the current of the first current source with the current of the second current source becomes in effect.

摘要： A voltage regulator is provided. The voltage regulator provides an output voltage that is proportional to a digital multi-bit select signal. The voltage regulator includes a coarse voltage regulator and a fine voltage regulator. The coarse voltage regulator provides a coarse output voltage based on an output of a voltage divider selected based on the most significant bits of the select signal. The fine voltage regulator provides the output voltage from the coarse output voltage. The output of the fine voltage regulator is adjusted by adjusting the output of an adjustable current source that is provided to a resistor that is coupled between the output and one of the inputs of the fine voltage regulator.

摘要： An impulse generator including first and second differentiators coupled in parallel to each other, for generating impulses by differentiating a clock signal, and first and second switches for transiting on and off the first and second differentiators respectively to selectively output the impulses generated by the first and second differentiators, and varying polarity of the impulses by changing a direction of a current flowing through load. Accordingly, the negative and positive impulses are selectively output according to the circuit state, reliability of the impulses is improved, and power consumption is reduced.
