Abstract: A clock data recovery circuit includes a deglitch filter circuit and a timer circuit. The deglitch filter circuit is configured to remove pulses of less than a particular duration from a data signal to produce a deglitched data signal. The timer circuit is coupled to the deglitch filter, and is configured to compare a duration of a pulse of the deglitched data signal to a threshold duration, and identify the pulse as representing a logic one based on the duration of the pulse exceeding the threshold duration.

Abstract: A clock data recovery circuit includes a deglitch filter circuit and a timer circuit. The deglitch filter circuit is configured to remove pulses of less than a predetermined duration from a data signal to produce a deglitched data signal. The timer circuit is coupled to the deglitch filter, and is configured to compare a duration of a pulse of the deglitched data signal to a threshold duration, and identify the pulse as representing a logic one based on the duration of the pulse exceeding the threshold duration.

Abstract: Methods and apparatus for DC-DC soft start are disclosed herein, an example DC-DC voltage converter includes at least two transistors to at least charge or discharge an inductor from an input source and to ground respectively, the inductor to output an output voltage. A synchronize and track circuit generates a bias current based on a reference voltage. An amplifier generates an error current based on an output voltage and the reference voltage. An oscillator oscillates at a switching frequency based on the bias current and the error current. A multiplexer selects between (1) a first input signal generated based on the switching frequency, and (2) a second input signal generated based on the switching frequency and the error current, for output as a reset signal. A latch provides a control signal to the at least two transistors based on the reset signal and the switching frequency.
