摘要： An imaging system includes an A/D converter including a holding unit holding a pixel signal as a voltage level, a comparator comparing the voltage level held with a reference level, a circuit capable of changing the voltage level so as to approach the reference level at first and second rates, wherein the voltage level is changed at the first rate to determine higher bits in accordance with inversion of a relationship between the reference level and the voltage level, after that, the voltage level is changed at the second rate to determine lower bits in accordance with inversion of the relationship between the reference level and the voltage level, and an adjusting unit which adjusts the voltage level during a period until the voltage level is changed at the second rate after determination of the higher bits so that the lower bits and the voltage level hold a linear relationship.

摘要： The present invention relates to a data sampling method: sampling a physical quantity according to a sampling frequency f s ≤ f sh , f sn = ζ max / ε being the upper limit of the sampling frequency; and a data sampling method and system: sampling a physical quantity with a sampling frequency satisfying Nyquist theorem, firstly performing digital low-pass filtering on an obtained sampled sequence, and then re-sampling, the re-sampling frequency f s ≤ ζ max / ε , where ε is the Z-domain error of a sampling system, and ζ max is the maximum error of an S-domain. The present invention also relates to a parameter identification method and system which firstly adopt the above data sampling method and system to obtain sampled data, and then utilize the sampled data to perform dynamic and/or static parameter identification. The data sampling method and system and the parameter identification method and system of the present invention solve technical difficulties such as relatively large errors in sampled data, digital control instability, and parameter identification failure.

摘要： A low cost, easily manufactured analog to digital converter uses MOS switching technology easily combined on an integrated circuit with other signal processing circuitry. An input capacitor stores an input analog voltage, and a pumping capacitor is switchably connected to the input capacitor to charge or discharge that input capacitor to a reference value. The number of charge or discharge events is used to generate a digital value for the input analog voltage.

摘要： A converter for converting an analog signal to a digital pulse comprises a switching capacitor (10) which is charged by a differential analog signal supplied to the switching capacitor (10) over an input circuit (12). The capacitor (10) is discharged over an output circuit (14) with the aid of a constant current supply (44). The charge level of the capacitor (10) is proportional to the analog signal so that the time it takes the capacitor to discharge to a selected low charge level is proportional to the analog signal. This time period is used by a microprocessor (50) to generate a digital pulse having a pulse width equal to the discharge time for the capacitor (10). The microprocessor (50) also selectively connects the input and output circuits (12, 14) to the capacitor (10) for respectively charging and discharging the capacitor.
