- 1. An amplifier containing an arrangement of capacitive elements to provide the function of a source degeneration inductor arrangement in determining the real part of the amplifier'"'"'s input impedance.
- 4. An amplifier comprising a transistor, having first, second and third terminals, and first and second capacitive elements, wherein the first capacitive element is located between the first terminal and one of the other two terminals and the second capacitive element is located between the second and third terminals such that the capacitive elements co-operate such that the real part of the amplifier'"'"'s input impedance is substantially provided by reactive elements.
