  • DC blocker for a high gain complex circuit
    Patent number: 9083281
    Abstract: An amplifying circuit comprises an analog amplifying circuit having an analog input for receiving an analog input signal to be amplified and an analog output for outputting an amplified analog signal, wherein the amplifying circuit comprises an implementation of a complex transfer function. A feedback circuit has a feedback circuit input and a feedback circuit output, wherein the feedback circuit comprises an implementation of an inverse transfer function that is an estimation of an inverse of at least a DC component of the complex transfer function of the analog amplifying circuit. The feedback circuit input is arranged for receiving a signal that is based on the amplified analog signal of the analog amplifying circuit. The analog circuit is arranged for receiving a bias signal that is based on the feedback circuit output.
