  • Wideband amplifier circuit having automatic gain and offset voltage control
    Patent number: 5218320
    Abstract: A wideband amplifier circuit having automatic offset voltage and gain control, the circuit comprising a main amplifier chain, a negative feedback loop for controlling gain, and a negative feedback loop for controlling and cancelling any possible offset voltage at its output, said main amplifier chain including a gain control amplifier block having a gain control input connected to the gain control negative feedback loop; wherein the gain control amplifier block is preceded in the main chain by a symmetrizer-adder block of fixed gain having a first input constituting the input of the amplifier circuit and a second input connected to the negative feedback loop for controlling and cancelling any possible offset voltage at the output.
