Three CMOS integrated circuits are presented that utilize metamaterial composite right/left handed (CRLH) transmission lines (TLs) for tunable zero insertion phase at 30 GHz. Initially, two passive fixed TL structures are realized followed by an active design using accumulation-mode NMOS varactors. An tunable insertion from -9deg to +27deg can be observed. Results suggest the possibility of zero,...
A 38 GHz cross-coupled differential LC-VCO has been designed and fabricated using the TSMC 0.18-mum CMOS process. A differential accumulation-mode MOS (AMOS) varactor structure is used, with a tuning range of 36.7 to 38.9 GHz. The differential varactor structure provides suppression of common-mode noise on the power supply and frequency control lines
A K-band low voltage, highly linear Gilbert cell mixer is presented in this paper. The goal of this work is to achieve highest possible linearity when the supply voltage is as low as 2 V. The proposed low voltage mixer topology has been experimentally verified with a down conversion mixer fabricated in a 0.18-mum CMOS process. Utilizing PMOS devices in the transconductance stage and using a 2 V supply...
