Ring oscillator for digital multilevel non-volatile memory |
摘要 |
An oscillator that can be used within a high voltage generation and regulation system for non-volatile memory. The system may comprise a charge pump that may have at least one pump and an oscillator. In one aspect the oscillator provides clock signals to the pump. The output of the oscillator may be disabled without turning off the clock generation. The oscillator may be a ring oscillator. In one aspect, the ring oscillator and the output stage may comprise inverters with a capacitor coupled to the output of the inverter. In one aspect, the ratio of the capacitors in the ring oscillator to the capacitor in the output stage determine the phase shift between the two clock signals. In another aspect, the capacitance of the capacitors are identical and a bias applied the ring oscillator and the output stage are radioed to adjust the phase between the two clock signals.
