Special electronically reconfigurable lossy/lossless integrator in application of functional generator

This paper deals with idea of an electronically reconfigurable integrator utilized in nonlinear application of functional generator and study of its features in this circuit. The integrator can be electronically readjusted to lossy and lossless type as well as this integrator also offers electronic tuning of time constant. Possibility of simple electronic reconfiguration provides generation of square wave and selection to generate triangular or exponential (relaxation) output waveforms in node of working capacitor. Intentions of synthesis and design were confirmed by PSpice simulations.
