Crosstalk Impact on CMOS Low Noise Amplifiers from RF to millimeter Wave

This work addresses crosstalk effects on three low noise amplifiers (LNAs) operating at different frequency bands, the S-band (2.4 GHz), the Ka-band (28 GHz), and the V-band (56 GHz). The LNAs were implemented using a 22nm FDSOI process and were extracted both as stand-alone circuits and considering operation onto the same die. The passive components were extracted using Ansys RaptorX. As to address the consequences of crosstalk on the LNA performance specific performance metrics, such as gain (S <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">21</inf> ), input matching (S <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">11</inf> ), noise figure (NF), linearity (1 dB Compression Point and Third Point Intercept) and power dissipation (P <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">dc</inf> ), were studied for each frequency band LNA and compared with their performance when they were operating onto the same die.
