Abstract
Recent advances in technologies like Internet of Things (IoT), Cognitive Radios (CR) and Software Defined Radios (SDR) require receiver front ends that act as robust communication links. With no possibility in using passive filtering elements for their limited configurability, such receivers need to be wideband. Thus, having to deal with blockers and interferers from every possible frequency band received by the front-end. So, they also need to have good linearity performance. For complete adjustability, these receivers need to be able to change their center operating frequency, filtration shape, bandwidth and order.
However, the state-of-the-art receiver architectures that are reconfigurable and highly linear usually end up being noisy. And those which already have low noise are not completely adjustable. The only adjustable parameters after fabrication would be the filter bandwidth and center frequency.
In this work, an architecture was proposed to be able to solve the tradeoffs of previous works in literature. It focused on a promising previous architecture based on the filtering by aliasing (FA) concept. Such a receiver suffered from a noisy performance. A solution is suggested to this problem. Backed up with concept review and simulation results.
Simulations with TSMC 65-nm CMOS technology showed a minimum achievable noise figure of 3.3 dB for a front end tuned at 500 MHz with 5 MHz RF BW and a Sinc filtration profile. For a Kaiser profile it gave 4.3 dB. This architecture retained its good linearity and matching characteristics, with S11 better than -10 dB.
