    Abstract: An adaptive driver includes a gate driver having at least one driving transistor for driving a control node of switching transistor(s) that includes an output node (OUT) which provides Vout. An adjustable current source is in series with the driving transistor, a high pass filter (HPF) is between OUT and ground for detecting a slew rate of the switching transistor and outputting a voltage pulse (Vslp) output having a peak voltage amplitude at least monotonically reflecting a slope of Vout during switching. Detection signal processing circuitry is coupled to the output of the HPF for processing Vslp and slew rate control circuitry has an input coupled to the output of the detection signal processing circuitry. The output of the slew rate control circuitry is coupled to the current source for controlling its current level for changing the slew rate of the switching transistor to provide a desired slew rate range.

    Abstract: A method for correcting the duty cycle of a clock signal uses two-dual-slope integrators with two comparators; each comparator is connected to both integrators and configured to include a “dead band” when the input pulse duty cycle is at or near 50%. One comparator detects when duty cycle is high and the other comparator detects when the duty cycle is low. When the duty cycle is within the “dead band” range, neither comparator goes valid. This provides an analog filter where the output comparators will not instantaneously switch between opposite duty cycle correction states. When the duty cycle is greater or less than 50%, the integrated voltages on the two integrators move in opposite directions producing twice the signal magnitude on differential inputs of the comparators, as compared with using a single integrator architecture.

    Abstract: A system includes an ADC that, based on a first clock signal, converts an analog signal into a digital signal. A first circuit generates a second clock signal based on the digital signal. An interpolator generates a phase delayed version of the second clock signal and a third clock signal. The third clock signal is generated based on the second clock signal and the phase delayed version and includes transitioning from the second clock signal to the phase delayed version. The third clock signal includes pulses each having a first pulse width and a pulse having a second pulse width. The second pulse width is different than the first pulse width due to the transition from the second clock signal to the third clock signal. A second circuit removes the pulse having the second pulse width from the third clock signal to generate the first clock signal.
