    摘要： Various embodiments allow for background calibration of channel-to-channel mismatch errors. In certain embodiments calibration is accomplished by comparing the output of I-ADCs against the output of a reference ADC and correlating the difference to a known function to obtain a correction signal that can be used to correct channel-to-channel mismatch errors.

    摘要： A comparator based circuit with effective offset cancellation includes first and second amplifiers and an offset capacitor operatively connected to the first and second amplifiers. An offset voltage source generates an offset voltage. A first switch connects the offset voltage source to ground during a first time period. The first amplifier generates an output voltage in response to the first switch connecting the offset voltage source to ground during the first time period. A second switch connects the offset capacitor to ground during a second time period. The first switch disconnects the offset voltage source from ground during a third time period, and the second switch disconnects the offset capacitor from ground during the third time period.

    摘要： A sample-data analog circuit includes a level-crossing detector. The level-crossing detector controls sampling switches to provide a precise sample of the output voltage when the level-crossing detector senses the predetermined level crossing of the input signal. A multiple segment ramp waveform generator is used in the sample-data analog circuits. The ramp waveform generator includes an amplifier, a variable current source, and a voltage detection circuit coupled to the current source to control the change in the amplitude of the current. The ramp generator produces constant slope within each segment regardless of the load condition. The sample-data analog circuit also utilizes variable bandwidths and thresholds.

    摘要： Described is a switched-capacitor network and method for performing an analog circuit function. The circuit includes a switched-capacitor network, a comparator, and a voltage-offset network. The switched-capacitor network includes multiple switches, each having a respective threshold voltage and connected to one of a high-limit voltage, a low-limit voltage, and electrical ground. A first comparator input terminal in communication with the switched-capacitor network is configured to receive a node voltage therefrom during a first phase. The second input terminal is configured to receive one of the high-limit voltage and the low-limit voltage. The voltage-offset network provides a voltage shift at the first input terminal setting an input reference level at a mid-level voltage with respect to the high-limit voltage and the low-limit voltage. The voltage shift enables the first terminal to receive full-swing voltages when the high-limit voltage is less than twice the threshold voltage, with power supply voltages below twice the threshold voltage.

    摘要： A sampled-data analog circuit includes a level-crossing detector. The level-crossing detector controls sampling switches to provide a precise sample of the output voltage when the level-crossing detector senses the predetermined level crossing of the input signal. The level-crossing detection may be a zero-crossing detection. An optional common-mode feedback circuit can keep the output common-mode voltage substantially constant.
