This article presents design and implementation of a 60-GHz millimeter- wave on-chip bandpass filter using a 0.18-μm standard CMOS process. The asymmetric compact microstrip resonator cell structure is used to design the filter with two transmission zeros. The input and output capacitors using multilayer coupling are added to create the passband. The die size of the chip is 0.85-0.64 mm2. The filter has a 3-dB bandwidth of about 15 GHz at the center frequency of 64 GHz. The measured insertion loss of the center-frequency is about 3.9 dB and the return loss is better than 10 dB within passband. The designed on-chip filter is useful for the integrated design of the 60-GHz CMOS single-chip RF transceiver.
