Generating reference currents compensated for process variation in non-volatile memories |
摘要 |
In a current reference generator device, a voltage reference generator stage generates a reference voltage (Vref) and an active element output stage receives the reference voltage (Vref) and outputs a reference current (Iref) as a function of the reference voltage (Vref). A control stage is operatively coupled to the voltage reference generator stage and to the active element output stage and controls a first trimmable parameter (m) associated to the voltage reference generator stage and a second trimmable parameter associated to the active element output stage, so as to compensate for changes in a value of the reference current (Iref) due to manufacturing process deviations.
