“…In communication systems, CPW in a ground-signal-ground (GSG) configuration is normally used for designing amplifiers [2][3][4][5], frequency doublers [6,7], mixers [8,9], power DACs (PDACs) [10,11] and interposer connections between different components [12,13]. Being different from CPW, CPS as well as ACPS are in a ground-signal (GS) configuration and they are used for designing baluns [14][15][16][17], antennas [18][19][20], and the electrodes of Mach-Zehnder modulators (MZMs) [21][22][23].…”
