Variable 360° Vector-Sum Phase Shifter With Coarse and Fine Vector Scaling
A CMOS vector-sum phase shifter covering the full 360° range is presented in this paper. Broadband operational transconductance amplifiers with variable transconductance provide coarse scaling of the quadrature vector ...
Low Power Communication RFIC Design For Applications In Biotelemetry
This thesis explores low power communication blocks for applications in biotelemetry. As wireless networks become more prevalent and demand for sensor networks increases, so does the need for low power wireless ...
