The designing of square pulse generators using pulseforming lines (PFLs) made up of identical L and C, was reviewed in this study. 14 different types of PFL were analyzed utilizing PSpice simulation results. These PFLs were characterized with respect to their distinct features: the number of forming lines (single or double), the circuit relationship of the PFL and load (parallel or series), the types of energy storage (current source, voltage source or a combination of both). The characteristic impedance, output parameters such as pulse width, voltage and current magnitudes, and power were derived for each scheme. The merits and demerits of the output parameters were also included.
