ABSTRACT:
This generator of periodic signals with exponential edges, which may be integrated at low cost, comprises a current source circuit connected to a capacitor and to a resistive element to supply them with currents having mutually correlated amplitudes, an amplifier interposed between the capacitor and the resistive element and adapted to maintain the voltage drop on the resistive element proportional to the voltage drop on the capacitor, and a switch device, connected in parallel to the capacitor and periodically switched off to allow the discharge of the capacitor.
