A Decade-Bandwidth Low-Noise Mixer RFIC with a Distortion-Canceling Output Amplifier
(2016-08-08)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 Conversion Gain Flatness of Transformer-Coupled Mixers
(2016-08-08)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 ... -
Method to Improve the Linearity of Active Commutating Mixers Using Dynamic Current Injection
(2016-08-08)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 ... -
Towards Intensity-Augmented SLAM with LiDAR and ToF Sensors
(2016-02-24)Although passive sensors are widely used for many mobile robotics applications that perform mapping and localization functions, there are many environments (e.g., mining and planetary) where active sensors are more practical. ... -
Variable 360° Vector-Sum Phase Shifter With Coarse and Fine Vector Scaling
(2016-08-08)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 ...
