Adjustable frequency oscillator circuit and relative calibration method |
摘要 |
An adjustable frequency oscillator circuit includes: an odd number of inverters connected so as to form a loop; a plurality of capacitive elements each connected to an output terminal of a respective inverter; and an output terminal, which supplies a signal oscillating at an oscillating frequency. The oscillator circuit further includes a calibration circuit for calibrating maximum currents which can be delivered by the inverters to the respective capacitive elements.
