摘要： A video signal processing system capable of adjusting errors and related methods are introduced. The video signal processing system and related calibration methods utilize the characteristic of periodic breaks of video signals to perform various kinds of calibrations including gain calibration of ADC, offset calibration of ADC, dc-level shifting of input signals, and quatization errors spreading by adding analog random signals to input video signals. The required high accuracy in video signal processing systems is achieved in the present invention with the claimed calibration methods.

摘要： The present invention provides a passive RFID chip with on-chip charge pumps for generating electrical power for the chip from radio frequencies. The passive RFID chip comprises an analog portion and a digital portion. The analog portion primarily comprises a voltage sensor and an AM data detector. The digital portion comprises a state machine digital logic controller. Incoming RF signals enter the chip via external antennas. The RF signals are converted into regulated DC signals by RF-DC converters with the voltage sensor. The RF-DC converters provide power for all the on-chip components and hence the chip does not require external power supply. The incoming RF signals are demodulated by demodulators and enter the AM data detector where the envelope transitions are detected. A voltage alarm is provided to ensure the voltage level does not drop below an operational level of the chip. The logic signals and programming data are controlled by the state machine digital logic controller and the timing signals are provided by an on-chip oscillator.
