- W2808977460 abstract "Significant improvements of low-cost energy-efficient integrated circuit designs with sensing, analog signal processing, power management, computation, and communication functions are required to support the envisioned Internet of Things (IoT). Considering the goal to produce more portable wireless terminals and devices that communicate with each other, a critical obstacle is that radio frequency (RF) front-ends consume excessive power in many emerging wireless devices. It is essential and challenging to create novel analog circuit design techniques with significant power reductions while maintaining adequate performance. Another trend is that soaring wireless connections and the associated interference signals increase the demand for highly linear analog circuits in receivers to avoid that the desired signals are distorted by unwanted mixing with interference signals. This problem motivates research efforts to improve the third-order intermodulation performance of RF front-end circuits to minimize signal distortions. The design approaches developed in this thesis work simultaneously address the challenges of achieving low power consumption and high linearity, especially for RF front-end circuits operating with supply voltages below 1V and having power consumptions below 1mW. In particular, this research focuses on a linearization technique for low-power active mixers, which are often the bottleneck of the overall linearity performance in RF receiver front-ends. The concepts are demonstrated with a 2.4GHz RF front-end composed of a low-noise amplifier and mixer. This RF front-end was designed and fabricated in 130nm complementary metal-oxide semiconductor (CMOS) technology." @default.
