Abstract
Systems, methods, circuits, devices, and apparatus including computer-readable mediums for managing reference voltages, e.g., with current compensation, in memory systems, e.g., non-volatile memory systems. In one aspect, an integrated circuit includes: an operational amplifier configured to receive input voltages and a supply voltage and output a control voltage based on the input voltages and the supply voltage; an output circuitry configured to receive the control voltage from the operational amplifier and the supply voltage, provide the input voltages to the operational amplifier, and output a reference voltage; and a compensation circuitry coupled to the output circuitry and configured to output a compensation current to compensate the output circuitry such that the reference voltage is substantially constant. The output circuitry is configured to generate the reference voltage based on the control voltage and the compensation current.
