Method to Improve the Conversion Gain Flatness of Transformer-Coupled Mixers
A 4-10 GHz, on-chip balun based current commutating mixer is proposed. Tunable resistive feedback is used at the transconductance stage for wideband response, and interlaced stacked transformer is adopted for good balance ...
A Decade-Bandwidth Low-Noise Mixer RFIC with a Distortion-Canceling Output Amplifier
This paper presents a 1-10 GHz low-noise downconvert mixer RFIC suitable for wideband receivers. A switched transconductor mixing core is adopted to reduce noise at high frequencies. By adding a series inductor to the RF ...
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 ...
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 ...
