A linearization technique for bipolar amplifiers based on Derivative
Superposition is presented. The proposed technique provides excellent
linearity, while having low sensitivity on the bias conditions. A
demonstrator circuit, along with a reference circuit using out-of-band
linearization for linearity comparison, have been designed and
implemented in a 0:25μm SiGe:C BiCMOS technology to show the
effectiveness of the proposed approach. Measured results show a
significant IM3 improvement up to compression compared to the reference
circuit.@en
