This paper presents a noise reduction technique using common-mode feedback in active CMOS mixers. The proposed decreases the noise, thus reducing common-to-differential conversion arising from mismatch and process variations. In addition, reduces sensitivity to process, voltage, temperature (PVT) variations due negative feedback. A theory is adopted analyze low-noise performance of technique. t...

In this paper, a low power ultra-wideband (UWB) CMOS LNA was designed exploiting source inductive degeneration technique operating in the frequency range of 3.1–10.6 GHz. In order to achieve low noise figure and high linearity simultaneously, a modified three-stage UWB LNA with inter-stage inductors was proposed. Forward Body-Biased (FBB) technique was used to reduce threshold voltage and power...

The main focus of this paper is to design a “Low noise amplifier” for radio frequency applications using MOS 180nm technology. In modern RF electronics, we rarely design an LNA in isolation. Rather, we view and design the RF chain as one entity, performing many iterations among the stages. A low power MOS low noise amplifier (LNA) working at 2.4GHz for ZigBee communication is presented in this ...

The dependency of RF performance on the local oscillator (LO) drive amplitude and DC bias is an important topic for mixers, especially as carrier frequency increases generation power thus becomes more complex. prediction mixer performance, without initial reliance full circuit simulations, can provide insights.
