Abstract
A signal driver circuit includes a first inversion driver, a second inversion driver and an emphasis driver. The first inversion driver is configured to receive a first signal, and output a second signal by inversion-driving the first signal. The second inversion driver is configured to receive the second signal, and output a third signal by inversion-driving the second signal. The emphasis driver is configured to receive the third signal, inversion-drive the third signal, and combine the inversion-driven signal to the first signal.
Claims10
A signal driver circuit comprising:
- a first inversion driver configured to receive a first signal, and to output a second signal by inversion-driving the first signal;
- a second inversion driver configured to receive the second signal, and to output a third signal by inversion-driving the second signal;
- and
- a transistor configured to receive the third signal to only pull-up drive the first signal.
A signal driver circuit comprising:
- 2n numbers of inversion drivers configured to output a second signal by sequentially inversion-driving a first signal, where n is an integer equal to or greater than 2;
- and
- an emphasis driver configured to inversion-drive the second signal, and to combine the inversion-driven signal to the first signal.
A signal driver circuit comprising:
- a first driver circuit configured to output a first output signal by inverting a first phase signal 2n number of times, to invert the first output signal, and to combine the inverted signal to the first phase signal,
- wherein n is an integer equal to or greater than 2.
A signal driver circuit comprising:
- a first inversion driver configured to receive a first signal, and to output a second signal by inversion-driving the first signal;
- a second inversion driver configured to receive the second signal, and to output a third signal by inversion-driving the second signal;
- and
- a transistor configured to receive the third signal to only pull-down drive the first signal.
