High-Linearity Bottom-Plate Mixing Technique With Switch Sharing for N-path Filters/Mixers
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A four-path filter/mixer for surface acoustic wave (SAW)-less frequency division duplex (FDD) radio receivers is proposed, targeting high linearity and compression requirements. A bottom-plate mixing technique improves linearity by reducing the gate-source voltage...

Low-noise optical receiver front-end using narrow-bandwidth TIA and cascaded linear equalizer
2017 Edition, August 1, 2017 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In this paper, the sensitivity of the optical receiver is revisited. An analytical expression that reveals the dependency of the sensitivity on both the data rate (f bit ) and the bandwidth shrinkage factor (n) is derived. The proposed sensitivity model provides guidelines for selecting the...
