摘要：
A circuit and corresponding method for providing a reference voltage are presented. The circuit includes a current source having a magnitude with positive temperature correlation connected to a node, and a diode element connected between the node and ground, where the reference voltage is provided from the node. The circuit also includes a variable resistance connected to receive an input indicative of the circuit temperature and through which the diode element is connected to the node. The value of the variable resistance is adjusted based upon the circuit temperature input. The circuit is useful for application as a peripheral circuitry, such as on a flash or other non-volatile memory and other circuits requiring an on-chip reference voltage source.
