چکیده مقاله:

In this paper a novel wideband amplifier based on a positive feedback is presented. The utilizing feedback network includes two capacitors and an emitter degeneration resistorwhich does not affect the low frequency behavior of the amplifier. Also a series- series mode is exploited to compensatethe miller effect of Cμ and to decrease the input capacitance. The proposed method is obtained a 200% gain bandwidth enhancement with respect to a simple differential pair and a 21% improvement considering other topologies in the literature.
