Semiconductor device and phase locked loop including the same |
摘要 |
Provided are a semiconductor device and a phase-locked loop (PLL) including the same. The semiconductor device including an output node from which an output signal is output, a first transistor which has a drain connected to the output node and is gated by a first signal to increase a voltage level of the output node, a second transistor which has a drain connected to the output node, is gated by a second signal which is a complementary signal of the first signal, and reduces the voltage level of the output node, a pull-up circuit which provides a first compensation current varying according to the voltage level of the output node to a source of the first transistor, and a pull-down circuit which provides a second compensation current varying according to the voltage level of the output node to a source of the second transistor. |

1. A semiconductor device comprising:
an output node from which an output signal is output; a first transistor which has a drain connected to the output node and is gated by a first signal to increase a voltage level of the output node; a second transistor which has a drain connected to the output node, is gated by a second signal which is a complementary signal of the first signal, and reduces the voltage level of the output node; a pull-up circuit which provides a first compensation current varying according to the voltage level of the output node to a source of the first transistor; and a pull-down circuit which provides a second compensation current varying according to the voltage level of the output node to a source of the second transistor. |
