This letter presents the design and implementation of a 24-/60-GHz millimeter-wave dual-band on-chip bandpass filter using a 0.18-μm standard CMOS process. The concept of quarter-wavelength stepped-impedance resonator (λ/4 SIR) is utilized to realize stopband characteristics at desired frequencies and reduce the chip size. The structure of the open-circuited dual-behavior resonators (OC-DBRs) produces one passband with two transmission zeros on either side. The size of the designed filter is 1.030 × 0.590 mm2.
