Patent ID: 7042284

Claim:
An operational amplifier arrangement comprising a first arrangement input terminal to which an input signal is supplied and a first arrangement output terminal, said operational amplifier arrangement further comprising: a non-linear amplifier having a pair of input terminals, one of which is coupled to said first arrangement input terminal, said non-linear amplifier further comprising an output terminal, a linear amplifier having a pair of input terminals, one of which is coupled to said first arrangement input terminal, said linear amplifier further comprising an output terminal, whereby the output terminal of said non-linear amplifier is coupled to the output terminal of said linear amplifier via a first series impedance, whereby the output terminal of said linear amplifier is coupled to the first arrangement output terminal via a first terminating impedance, and whereby the operational amplifier arrangement further comprises a first active back termination arrangement coupled between the first arrangement output terminal and either one of said pair of input terminals of said linear amplifier.
