INPUT PARAMETERS

• w : width of ic_microstrip line (meters)
• l : lentgh of ic_microstrip line (meters)
• tox : oxide thickness (meters)
• h : substrate thickness (meters)
• er : substrate relative permitivity
• sigmas : substrate conductivity (1/ohm-m)
• tmet : metal thickness (meters)
• rho : resistivity of wire (relative to copper)
• rough : conductor surface roughness (meters-rms)
• f : synthesis frequency (Hz)

OUTPUT VALUES

• z0 : calculated characteristic impedance (Ohms)
• keff : calculated effective relative permitivitty
• elen : calculated electrical length of the line (degrees)
• loss : calculated loss of the line (dB)
• L : calculated inductance per length (Henries/meter)
• R : calculated resistance per length (Ohms/meter)

DESCRIPTION

Function to analyze the electrical characteristics of a single integrated circuit microstrip transmission line. The physical dimensions of the microstrip line are given as inputs and the characteristic impedance, effective dielectric constant, loss and open circuit end correction are calculated.
