ABSTRACT:
This high-precision oscillator stage, with reduced response times, includes only NPN transistors on the signal path and comprises a threshold detector circuit connected to a first and to a second threshold voltage and to the output of the stage so as to generate a differential voltage output signal which switches when each voltage threshold is reached, a control and memory circuit comprising a differential voltage detector connected to the output of the threshold detector and generating a charge and discharge signal depending on the state of the circuit, a memory element controlled by the differential voltage detector to maintain the charge and discharge states and an output driving circuit connected to the control and memory circuit so as to supply an external capacitor with constant currents so as to alternately and periodically charge and discharge the capacitor.
