ABSTRACT:
Aspects provide for the broadband amplification of RF signals. Other aspects provide for the conversion of single ended input to differential output. Various aspects provide for tuning the response to a particular frequency band. Other aspects provide for various transconductance elements. In several aspects, broadband current to voltage converters and voltage to current converters are presented. Some implementations incorporate a buffer circuit, and various implementations incorporate feedback circuits.
