摘要： An apparatus for controlling slew rate is coupled to two adjustable voltage rails. The output of the apparatus is coupled to the gate of a switching element. By employing two adjustable voltage rails, the slew rate of the switching element is proportional to the voltage difference between the first adjustable rail and the second adjustable rail. The slew rate control apparatus can be applied to a variety of switching elements including N channel Field Effect Transistors (NFETs), P channel Field Effect Transistors (PFETs), current mode logic circuits and level shifter circuits.

摘要： A noise shaper that compares an input signal to a feedback output signal, which is a truncated version of the input signal, and generates the difference between the two signals (i.e., the error). The noise shaper then integrates the errors by adding to the error multiple of its delayed versions, and quantizes the integrated errors in such a way that the spectrum of the quantization noise is shaped toward high frequencies to be removed by a LC low-pass filter used in conjunction with the noise shaper. The low frequency content of the desired signal is mostly unaffected.

摘要： A method of controlling a regulator includes turning on a first driver during a first cycle for a first time period. A second driver is turned on during the first cycle for a second time period. The first and second drivers are off during the first cycle for a third time period. The first time period is adjusted to become an adjusted first time period for a second cycle based on a ratio and a voltage difference between a peak value of the output voltage and a first voltage during the first cycle. The ratio refers to the first time period over the first time period and the second time period.
