Abstract:

Very high-speed picosecond range pulse transmission along a coplanar wave guide CPW integrated in a monolithic microwave integrated circuit MMIC is analyzed in the time domain, changing the input excitations, conductivity of the epitaxial layer, and terminating conditions. The time domain waveform is obtained by inverse discrete Fourier transform IDFT of the frequency domain data, namely, complex characteristic impedance and propagation constant. The full wave mode-matching method MMM is employed to analyze the dispersion of the CPW. A simple wide band matching scheme is found to be effective to make the slow-wave CPW a viable circuit element in applications such as a delay line or an interconnection line. Knowing the device processing data and physical dimensions, a designer should benefit from the present analysis that simulates the transmission of a very high-speed pulse on an MMIC CPW under various terminations.
