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 ...
Method to Improve the Linearity of Active Commutating Mixers Using Dynamic Current Injection
A double balanced (DBM) CMOS mixer providing high linearity is presented in this paper. A cross-coupled pair used in the IF stage of the mixer to dynamically inject current into the to mixer provide a high linearity. The ...
