High-Performance Slow-Wave Transmission Lines With Optimized Slot-Type Floating Shields

Abstract: A novel slow-wave transmission line with optimized slot-type floating shields in advanced CMOS technology is presented. Periodical slot-type floating shields are inserted beneath the transmission line to provide substrate shielding and to shorten the electromagnetic (EM) propagation wavelength. This is the first study that demonstrates how the wavelength, attenuation loss, and characteristic impedance can be adjusted by changing the strip length (SL), strip spacing (SS), and metal layer position of the slottyp… Show more

“…A slow-wave coplanar waveguide transmission lines, combining the advantages of both coplanar transmission lines and microstrip lines, is reported [11] to create high-performance passive components for millimeter wave integrating circuits. To achieve a slow wave, periodical slottype floating shields are used to enable a reduction in a chip area while still maintaining high performance.…”

“…With the increase of operation frequency, how to build a high performance matching network with less attenuation loss, small area and shield between signal line and underlying substrate is the primary problem to be solved. [5][6][7] The patterned ground shield (PGS) is commonly used for substrate shielding. However, when the operation frequency increases, especially beyond 20 GHz, the quality factor with PGS degraded further.…”
