Abstract: An encoder uses an input file of data and a key to produce an output symbol. An output symbol with key I is generated by determining a weight, W(I), for the output symbol to be generated, selecting W(I) of the input symbols associated with the output symbol according to a function of I, and generating the output symbol's value B(I) from a predetermined value function F(I) of the selected W(I) input symbols. An encoder can be called repeatedly to generate multiple output symbols. The output symbols are generally independent of each other, and an unbounded number (subject to the resolution of I) can be generated, if needed. A decoder receives some or all of the output symbols generated. The number of output symbols needed to decode an input file is equal to, or slightly greater than, the number of input symbols comprising the file, assuming that input symbols and output symbols represent the same number of bits of data.

Calibrating the ADC with the variable calibration source increases the accuracy of the ADC.

Abstract: In described embodiments, a communication system employing, for example, clock and data recovery (CDR) detects and applies correction for DC offset in an input data stream signal, termed as “DC offset calibration”. DC offset calibration applies static calibration for DC offset in input circuits, such as an input amplifier and detection latches, without input data, and applies statistical calibration for DC offset during operation with an input data stream to correct for dynamic shifts in DC level. Such DC offset calibration employs data eye measurements of the input data stream for detection of DC offset, and applies an opposite DC offset to maintain a relatively balanced data eye during live traffic.

Abstract: A hybrid Analog-to-Digital Converter (ADC) has a binary-weighted capacitor array and a sub-voltage capacitor array that are coupled together by a coupling capacitor. The sub-voltage capacitor array uses a minimum capacitor size that matches the minimum capacitor size of the binary-weighted capacitor array. The coupling capacitor is double the minimum size and reduces a voltage effect on a charge sharing line by half. Second coupling capacitors in the sub-voltage capacitor array each reduce the voltage effect by half, so that first, second, and third sub-voltage capacitors in the sub-voltage capacitor array produce ½, ¼, and ? voltage swings using the minimum size capacitance. Only MSB capacitors in the binary-weighted capacitor array sample the analog input voltage. During conversion, MSB's from a Successive-Approximation-Register (SAR) are applied to binary-weighted capacitors while LSB's are applied to sub-voltage capacitors.
