摘要： Methods, systems and devices for dynamically controlling resolution of an analog-to-digital converter (ADC). The ADC receives an analog input signal and outputs digital data. A statistical unit coupled to the ADC obtains samples of the output signal and transmits a control signal to the ADC to adjust the resolution of the ADC. The control signal is generated by the statistical unit based on a comparison of at least one performance indicator with a target performance level. The at least one performance indicator is calculated using the samples.

摘要： The present disclosure provides a system, circuit, and method for correcting clock skew in time-interleaved analog-to-digital converters. At least two clock signals are received along respective channels. A delay of a first channel, carrying a first clock signal, is accounted for by applying one or more first adjustment factors to the channels until an edge of the first clock signal is aligned with a transition point of a reference signal. The first clock signal is swapped to the second channel, and vice-versa. A value of the reference signal as sampled by the first clock signal is compared to values of the reference signal as sampled by the second clock signal to determine a skew of the second channel vis-à-vis the first channel, and one or more second adjustment factors are applied to the second channel based on the determined skew of the second channel.

摘要： Apparatus and methods are taught for quickly determining whether a Loss of Signal (LOS) condition has occurred for a receiver which includes an internal reference clock, a LOS circuit and a Clock and Data Recovery (CDR) circuit. The CDR circuit recovers the clock and data of an incoming signal. However, the LOS circuit can determine whether a received incoming signal includes an active signal, independent of said CDR circuit such that it samples said incoming signal utilizing said internal reference clock to determine a loss of signal prior to said CDR recovering the clock of said incoming signal. The LOS circuit includes an analog voltage threshold stage which samples the incoming signal, and produces at least one sample stream indicative of transitions in the incoming signal. The LOS circuit further includes a digital transition stage which counts transitions in order to discriminate between an active signal and noise.
