“…A CS-CPW is an efficient way of implementing a coupled line in silicon technology [3] [4]. The CS-CPW consists of two signal lines, side-ground lines in both sides of the signal lines which serve as the well-defined ground return current paths for the even-mode signal propagation, and gridded metal shields under the signal and ground lines.…”

“…Modeling of the CS-CPW structure by computer simulations is computationally heavy and time-consuming. Therefore, an efficient modeling methodology is proposed in [4] and successfully verified in [3]. The modeling approach divides the electromagnetic (EM) simulations of the CS-CPW structure into four parts, at first, it divides into odd-and evenmode analysis, and each mode is further decoupled into oddand even-mode R & L and C & G analysis.…”

In this paper, we have presented a design of onchip millimeter-wave 3-dB quadrature coupler that utilizes the coupled slow-wave coplanar waveguide (CS-CPW). The designed CMOS coupler covers the whole E-and W-band and occupies a silicon area of only 0.0115 mm 2 which is significantly smaller compared to the conventional microstrip-line-based Lange couplers. Measurement of the quadrature coupler shows a -3.5 dB through and a -4.4 dB coupling at 90 GHz. A less than ±1-dB amplitude and a ±4 • phase errors from 55 to 110 GHz are recorded.
