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.
Claims22
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
- an emphasis driver configured to receive the third signal, to inversion-drive the third signal, and to combine the inversion-driven signal to 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 1;
- 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 1.
A signal driver circuit comprising:
- a first main driver configured to generate a first intermediate signal by inverting a first phase signal, and to generate a first output signal by inverting the first intermediate signal;
- a second main driver configured to generate a second intermediate signal by inverting a second phase signal, and to generate a second output signal by inverting the second intermediate signal, wherein the second phase signal has a phase difference of 90 degrees from the first phase signal;
- and
- a first emphasis driver configured to invert the second phase signal, and to combine the inverted signal to the first phase signal;
- or configured to invert the second intermediate signal, and to combine the inverted signal to the first intermediate signal;
- or configured to invert the second output signal, and to combine the inverted signal to the first output signal.
