Abstract
Systems, methods, circuits, devices, and apparatus including computer-readable mediums for managing startups of bandgap reference circuits in memory systems, e.g., non-volatile memory systems. In one aspect, an integrated circuit includes: a power supply switch configured to receive an original supply voltage and provide a controlled supply voltage controllable by an enabling signal, an operational amplifier configured to receive input voltages and the controlled supply voltage and output a gate control voltage, output circuitry configured to receive the gate control voltage and the controlled supply voltage, provide the input voltages to the operational amplifier, and output a reference voltage, and initialization circuitry coupled to the power supply switch, the operational amplifier, and the output circuitry and configured to initialize the controlled supply voltage and the gate control voltage to ground based on the enabling signal, such that the reference voltage increases from ground to a target voltage during a startup.
