Voltage regulator for a flash memory |
摘要 |
The invention provides a voltage regulator. The voltage regulator (100) of the invention includes a comparison circuit (20) and a voltage divider circuit (110). The voltage divider circuit (110) has a PMOS transistor (T6) connected to a voltage source (VDD) and resistors (R1, R2, R3, R4, R5 and R6) serially connected between the transistor (T6) and a reference voltage. A feedback voltage generated from a node (N3) between resistors R4 and R5 is provided to the comparison circuit (20). In addition, a middle voltage (Vm) generated from a node (Nc) of the resistors is provided to a well region, so the parasitic capacitance is reduced. |
