Systems and methods which implement a transconductor replica feedback (TRF) block in a transconductor circuit are shown. In accordance with embodiments, the TRF block comprises a feedback transistor disposed as a replica of a corresponding transconductance transistor of the transconductor circuit. The TRF block provides enhanced looking-in degeneration impedance for the transconductor circuit, thereby allowing for higher linearity and lower power at the same time. TRF transconductors of embodiments can be implemented in, or otherwise applied to, various different circuits such as LNAs, filters, etc. |
