| Stdio-Wcalc: ic_microstrip_syn ic_microstrip_syn - Integrated circuit microstrip transmission line synthesis ## SYNOPSIS ic_microstrip_syn z0 w h l tmet rho rough er tand f flag ## PARAMETERS ### INPUT PARAMETERS z0 : desired characteristic impedance (Ohms) w : width of ic_microstrip line (meters) h : substrate thickness (meters) l : lentgh of ic_microstrip line (meters) tmet : metal thickness (meters) rho : resistivity of wire (relative to copper) rough : conductor surface roughness (meters-rms) er : substrate relative permitivitty tand : substrate loss tangent f : synthesis frequency (Hz) flag : indicates which parameters should be optimized flag=1 : synthesize the metal width flag=1 : synthesize the substrate thickness flag=2 : synthesize the oxide thickness ### OUTPUT VALUES w_out : calculated metal width h_out : calculated substrate thickness tox_out : calculated oxide thickness l_out : calculated metal length ## DESCRIPTION Function to synthesize the physical dimenstions of a single ic_microstrip transmission line to achieve a desired characteristic impedance and electrical length. The desired characteristic impedance and some of the physical dimensions of the ic_microstrip line are given as inputs and the remaining dimensions are calculated. The model accounts for dispersion (frequency dependent propagation velocity). ``
