Auto-Calibrating Demodulator, Associated Method and TV Receiver |
摘要 |
A demodulator comprises a reference voltage generating circuit for generating a reference voltage, a reference resistor for converting the reference voltage to a reference current, a current digital-to-analog converter (IDAC) for receiving a digital code and generating an output signal, a comparison apparatus for comparing the reference voltage with the output signal to generate a comparison output, and a calibration apparatus for updating the digital code according to the comparison output to calibrate the IDAC. |
