IFA consists of 6-stages amplifier with tunable gain, AGC system, linear output buffer for differential analog output.
Gain is sequentially reduced from the last stage to the first stage. This method allows to keep a low noise figure in wide gain range.
The IFA is designed using TSMC 65nm CRN65LP technology.
