A 53.5-62-GHz wideband CMOS low-noise amplifier (LNA) with excellent phase linearity property is reported. Current-sharing technique is adopted to reduce power dissipation. The LNA (STD LNA) consumed 29.1 mW and achieved input return loss (S11) of -10.3~ -19.5 dB, output return loss (S22) of -13.8~ -27.8 dB, forward gain (S21) of 8.1~ 11.1 dB, and reverse isolation (S12) of -49.9~ -60.2 dB over the...
A low-insertion-loss V-band CMOS bandpass filter is demonstrated. The proposed filter architecture has the following feature: the low-frequency transmission-zero (omegaz1) and the high-frequency transmission-zero (omegaz2) can be tuned by the series-feedback capacitor Cs and the parallel-feedback capacitor Cp, respectively. To reduce the substrate loss, the CMOS process compatible backside inductively-coupledplasma...
In this brief, we demonstrate that high-quality-factor and low-power-loss transformers can be obtained if the optimized pattern ground shields (OPGS) of polysilicon is adopted and the CMOS process-compatible backside inductively coupled-plasma (ICP) deep-trench technology is used to selectively remove the silicon underneath the transformers completely. OPGS means that the redundant PGS of a traditional...
