  • Differential amplifier and method for the operation of a differential amplifier
    Patent number: 8476974
    Abstract: A differential amplifier comprises a first amplifier (A1) with a signal input (Inp) and a signal output (Out1) that is fed back to a first feedback input (In1) of the first amplifier (A1) and is also connected to a first output (outp) of the differential amplifier. Furthermore, a buffer circuit (Buff) is connected to the first output (outp). A nonlinear resistor circuit (Rnl1, Rnl2) is coupled via a first output node (Vmid1) with the first output (outp) and via a second output node (Vmid2) with the buffer circuit (Buff).
    Type: Grant

  • Amplifier arrangement and method for amplifying a signal
    Patent number: 7791411
    Abstract: An amplifier arrangement and a method for amplifying a signal, the arrangement including a transistor to amplify an input signal and to provide an intermediate signal. The intermediate signal is amplified to form an output signal which is fed back to the transistor.
