In this article, we demonstrate a low-insertion-loss V-band (50-75 GHz) bandpass filter with two finite transmission zeros by standard 0.13 mu m CMOS technology. The proposed filter architecture has the following feature: the low-frequency transmission-zero and the high-frequency transmission-zero can be tuned by the series-feedback capacitor C(s) and the parallel-feedback capacitor C(p) respectively. Besides, low-insertion-loss is achieved by adopting thick microstrip-line (MSL) with optimized ground-plane pattern as the needed inductors to minimize the metal and substrate loss. This filter achieved insertion-loss (1/S(21)) lower than 3 dB m,er the frequency range of 52.2-76.7 GHz. input return loss (S(11)) better than -10 dB over the frequency range of 50.2-80.6 GHz, and output return loss (S(22)) better than -10 dB over the frequency range of 50.2-77.3 GHz. The minimum insertion-loss was 2.18 dB at 63.5 GHz, an excellent result for a V-band CMOS bandpass filter. The chip area was only 0,466 x 0.307 mm(2), i.e., 0.143 mm(2), excluding the rest pads.
