V. Aristov. Mathematical Description of the Operation of a Step-Recovery-Diode-Based Pulse Generator Circuit. Automatic Control and Computer Sciences, 2018, No. 6. The paper describes the operation of a classic step-recovery-diode-based pulse generator circuit using differential equations. The circuit has parasitic inductances and capacitors for both circuit elements and the diode in addition to standard discrete elements necessary for pumping the diode and generating a sharp edge. The results are compared with experimental data.
