<p>A low supply voltage oscillator circuit (4) of the type which comprises at least one capacitor (C1,C2) to be controlled, connected between first (VDD) and second (GND) voltage references, and a circuit for charging and discharging the capacitor to be controlled. The oscillator circuit (4) of the invention comprises at least first (A) and second (B) stages having symmetrical structures in a mirror-image configuration and being connected between the first voltage reference (VDD) and the second voltage reference (GND) and connected together through a memory element (FF) and respective primary switches (N3,N4) for alternately charging in a controlled fashion said capacitors (C1,C2). <IMAGE></p> |
