Noise reduction device and semiconductor device having the same |
摘要 |
A semiconductor device includes a first terminal for receiving a first signal; a second terminal for receiving a second signal having more restriction than the first signal with respect to a delay upon transmitting to an internal circuit; a first noise reduction circuit; and a second noise reduction circuit. The first noise reduction circuit includes a first Schmitt circuit for receiving the first signal from the first terminal; and an output signal adjusting unit for adjusting an output signal of the first Schmitt circuit when the output signal is maintained for a specific period of time after the output signal is varied. The second noise reduction circuit includes a second Schmitt circuit for receiving the second signal from the second terminal; and an input signal adjusting unit for adjusting the second signal input to the second Schmitt circuit according to a fluctuation of a power source voltage. |
