  • Fully integrated offset compensation feedback circuit
    Patent number: 7043206
    Abstract: An offset correction analogic circuit capable of compensating the offset of a digital baseband is described. The circuit comprises analog means to receive an output differential signal issued from a differential signal path. The differential signal path may be a baseband filter as used in digital communication systems. The baseband filter inputs an input differential signal having an offset to be compensated. The output differential signal is fed into an analog integrator to generate a pulsed signal either on a first output line or on a second output line according to the polarity of the output differential signal. The pulsed signal is then integrated into a switched capacitor and a differential compensation offset signal is issued. The frequency of the pulsed signal is preferably proportional to the voltage value of the output differential signal. The compensation offset signal may be summed with the input differential signal into a summing circuit.
