Abstract :
The paper reports a highly repeatable 10-bits 3.8 GHz phase shifter implemented in a standard 0.35 μm SiGe technology for high precision applications. The prototype principle of operations and design are thoroughly described and demonstrated. The generated 0.35° phase step exhibits a rms error lower than 0.32°, mainly determined by the PLL inserted in the architecture.
