Abstract
A receiver circuit of a semiconductor apparatus includes a first sense amplifier, a level restriction unit, and a second sense amplifier. The first sense amplifier amplifies an input signal in response to a clock signal and generates a first signal with a voltage swing between a first level and a second level. The level restriction unit receives the first signal and generates a correction signal with a voltage swing between the first level and a third level. The second sense amplifier amplifies the correction signal in response to the clock signal and generates a second signal with the voltage swing between the first level and the second level.
Claims14
A receiver circuit of a semiconductor apparatus, comprising:
- a first sense amplifier configured to amplify an input signal in response to a clock signal and generate a first signal that swings between a first voltage level and a second voltage level;
- a level restriction unit configured to receive the first signal and generate a correction signal that swings between the first voltage level and a third voltage level;
- and
- a second sense amplifier configured to amplify the correction signal in response to the clock signal and generate a second signal that swings between the first voltage level and the second voltage level.
A receiver circuit of a semiconductor apparatus, comprising:
- a first sense amplifier configured to amplify an input signal in response to a clock signal and output a first signal;
- a level restriction unit configured to receive the first signal and generate a correction signal with a same voltage swing regardless of a voltage swing of the first signal, wherein the level restriction unit has a smaller amplification range than the first sense amplifier;
- and
- a second sense amplifier configured to amplify the correction signal in response to the clock signal and output a second signal.
A method for receiving a signal, comprising:
- amplifying an input signal and generating a first signal pair in response to a clock signal;
- receiving the first signal pair and generating a correction signal pair with a same voltage difference regardless of a voltage difference of the first signal pair, wherein the correction signal pair is amplified with a smaller amplification range than the first signal pair;
- and
- amplifying the correction signal pair and generating a second signal pair in response to the clock signal.
