A wideband InP Gilbert-cell mixer using capacitive degeneration and current bleeding technique

Hua Xu, Wenxiang Zhen, Shurui Cao, Yongbo Su, Zhi Jin
2021 IEICE Electronics Express  
This letter presents a wideband and high conversion gain mixer based on Gilbert-cell in InP DHBT process.  ...  Capacitive degeneration is introduced to increase the bandwidth of the mixer with no voltage drop and few cost of area. Current bleeding technique is employed to improve conversion gain.  ...  This letter presents a wideband and high conversion gain mixer based on Gilbert-cell.  ...

A Reconfigurable Analog Baseband Circuitry for LFMCW RADAR Receivers in 130-nm SiGe BiCMOS Process

Jingyu Han, Yu Jiang, Guiliang Guo, Xu Cheng
2020 Electronics  
The topology includes a course gain tuning pre-amplifier, a folded Gilbert variable gain amplifier (VGA) with a symmetrical dB-linear voltage generator and a 10-bit R-2R DAC for fine gain tuning, a level  ...  The analog baseband chip is fabricated using 130-nm SiGe BiCMOS technology.  ...  In essence, the Gilbert cell adjusts its gain via the current switching technique, but the difference between current switching and Gilbert cell lies in the current feeding through load resistors.  ...
