Patent ID: 7639079

Claim:
A wideband amplifier having an amplifier input terminal and an amplifier output terminal, comprising: at least one transistor coupled to said amplifier input terminal; at least first and second impedance elements coupled between said amplifier input terminal and said amplifier output terminal; and a feedback signal path comprising the at least first and second impedance elements and operative to convey a feedback signal transmitted between said amplifier output terminal and said amplifier input terminal by way of said first and second impedance elements, wherein said feedback signal varies in accordance with changes in an impedance of each of said first and second impedance elements as a function of a frequency of an input signal applied to the amplifier input terminal, a value of each of said first and second impedance elements being adapted so as to peak a frequency response of said amplifier; wherein said at least one transistor comprises an input transistor having a transistor input terminal, wherein the amplifier further comprises a transistor feedback loop coupled to said input transistor to provide said feedback signal, said feedback loop comprising a feedback resistor and a feedback capacitor, said feedback resistor and said feedback capacitor being coupled in parallel with each other.
