Power-up reset circuits and semiconductor devices including the same
摘要：
A power-up reset circuit includes a sensing circuit and an output circuit. The sensing circuit outputs a node voltage in response to an external power supply voltage. The output circuit outputs a voltage sensing signal in response to the node voltage. A signal generation circuit outputs a reset signal in response to the voltage sensing signal. A first resistance adjustment circuit adjusts the level of the node voltage in response to an externally input first control signal. A second resistance adjustment circuit adjusts the level of the voltage sensing signal in response to an externally input second control signal.
