Rf Cmos Receiver Front-End Using A Reflex Amplifier, Radovan Kuzet
Theses and Dissertations - UTB/UTPA
A concept for an RF-CMOS receiver with reflex topology is developed and tested, using OrCad as the primary design and simulation tool. The main idea of the reflex topology is to reuse a Low Noise Amplifier (LNA) stage in the circuit and thus eliminate one high power consumption stage. A Gilbert cell is used for down conversion, with the benefit of low noise and low power while maintaining gain. A set of passive diplexers allows reuse of the LNA at the RF and IF. The complete circuit was simulated using 0.18 micron and 0.5 micron AMI technology. Parameters for the …
