Abstract From the Canadian patent

A DAC-based voltage regulator system for a non-volatile memory device comprises a charge pump circuit having an enable input and a voltage output node. A voltage-to~ current converter has an input coupled to the voltage output node and an output coupled to a virtual ground node. A current source is coupled to the virtual ground node and sinks one of a plurality of currents in response to states of a plurality of digital input signals. A transconductance amplifier has an inverting input at the virtual ground node a non-inverting input coupled to a reference voltage potential and an output. , A comparator has a first input coupled to the output of the transconductance amplifier, a …

Why it's free to use

  • Filed September 9, 2003. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended September 9, 2023.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 9, 2025.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
