Supply-glitch-tolerant voltage regulator with current generators
The patent US12045075B2 describes a voltage regulator designed to output a regulated voltage while maintaining stability during power supply glitches. Central to its design is an output transistor, which is connected to an output voltage node, and a series of components including a bypass capacitor, a compensation capacitor, and a limiting resistor. The limiting resistor is specifically configured to restrict reverse current flow from the compensation capacitor, ensuring that any voltage drop on the gate of the output transistor remains within acceptable limits. The impedance of this limiting resistor is less than that of two current generators connected to the system, which helps maintain the integrity of the regulated output. Additionally, the design incorporates a diode to prevent reverse current from the bypass capacitor to the power supply node, enhancing the regulator's reliability.
Further enhancements to the voltage regulator include a feedback circuit that adjusts the voltage on a node between the limiting resistor and the first current generator based on a reference voltage and the output voltage level. The compensation capacitor is sized to ensure that any voltage drop due to net charge loss remains below a predetermined threshold. The patent also specifies that the output transistor can be an n-type transistor, and the overall configuration is aimed at ensuring that the voltage regulator can effectively manage transient conditions, thereby providing a stable output voltage even during brief power supply interruptions. This innovative design is applicable in integrated circuit systems that require low-dropout regulation, ensuring consistent performance across various electronic applications.
