Abstract

The article discusses the use of low-power voltage-controlled-oscillator (VCO) circuitry with high-frequency silicon CMOS semiconductor technology to provide effective signal generation for a large range of wireless applications. By incorporating capacitive feedback and forward-body-bias (FBB) techniques in a cross-coupled CMOS VCO approach, improvements in output swing and phase noise can be achieved.

Abstract

The article presents information on a design for low-power integrated RF front thatuses a current-reuse low-noise amplifier (LNA) and a single-balanced mixer. The design employs a current-reuse low-noise amplifier and switch-pased single-balanced frequency mixer. It is stated that the need for low-power radio electronics continues to increase rapidly with the rapid growth of wireless technology.

Abstract

The article focuses on the design of broadband frequency-upconversion mixer for 1.0-10.6 gigahertz (GHz) of wireless applications. It makes use of the cross-coupling post-distortion technique (CCPFT). The mixer consumes only five megawatts of power making it suitable for multiple-band ultrawideband (UWB) communications systems and software-defined radios (SDRs).
