Abstract: A quad signal generator circuit generates four 2N-1 bit control signals in response to a 2N-1 bit thermometer coded signal. A digital-to-analog converter (DAC) circuit has 2N-1 unit DAC elements, with each unit DAC element including four switching circuits controlled by corresponding bits of the four 2N-1 bit control signals. Outputs of the 2N-1 unit DAC elements are summed to generate an analog output signal. The quad signal generator circuit controls a time delay applied to clock signals relative to the 2N-1 bit thermometer coded signal and a time delay applied to the 2N-1 bit thermometer coded signal relative to the delayed clock signals in logically generating the four 2N-1 bit control signals. The analog output signal may be a feedback signal in a sigma-delta analog-to-digital converter (ADC) circuit that includes a multi-bit quantization circuit operating to quantize a filtered loop signal to generate the 2N-1 bit thermometer coded signal.

Abstract: A quantizer generates a thermometer coded signal from an analog voltage signal. Data weighted averaging (DWA) of the thermometer coded signal is accomplished by controlling the operation of a crossbar switch controlled by a switch control signal to generate an output DWA signal. The output DWA signal is latched to generate a latched output DWA signal which is processed along with bits of the thermometer coded input signal in feedback loop to generate the switch control signal. The latching of the output DWA signal is performed in an input register of a digital-to-analog converter which operates to convert the latched output DWA signal to a feedback analog voltage from which the analog voltage signal is generated. The switch control signal specifies a bit location for a beginning logic transition of the output DWA signal cycle based on detection of an ending logic transition of the latched DWA signal.

Abstract: A system for automated classifying of electronic messages is disclosed. The system may receive an electronic message comprising a text including a message body and a metadata. The system may determine a case status based on the metadata and extract a set of events form the message body in response to the case status. The system may determine a case type based on the set of events and a set of case types. The system may generate a new case event in a case management system based on the case type.

Abstract: A quad signal generator circuit generates four 2N?1 bit control signals in response to a sampling clock and a 2N?1 bit thermometer coded signal. A digital-to-analog converter (DAC) circuit has 2N?1 unit resistor elements, with each unit resistor element including four switching circuits controlled by corresponding bits of the four 2N?1 bit control signals. Outputs of the 2N?1 unit resistor elements are summed to generate an analog output signal. The quad signal generator circuit controls generation of the four 2N?1 bit control signals such that all logic states of bits of the four 2N?1 bit control signals remain constant for at least a duration of one cycle of the sampling clock. The analog output signal may be a feedback signal in a sigma-delta analog-to-digital converter (ADC) circuit that includes a multi-bit quantization circuit operating to quantize a filtered loop signal to generate the 2N?1 bit thermometer coded signal.
