ABSTRACT:
An amplifier comprises a common-base transistor 1 and a common-emitter transistor 2. The transistor 1 is arranged to receive an input signal applied to an input terminal 8 by an inductor 12 connected to its emitter. The transistor 2 is arranged to receive the input signal by a capacitor 13 connected to its base electrode. The transistors 1 and 2 are biased by a current mirror arrangement comprising a transistor 3 and a current source 16. Differential current output signals are provided on the collectors of the transistors 1 and 2.
