Abstract: To stably operate a negative-voltage level shifter even when a voltage value of a high level of an input signal is lowered, a negative-voltage level shifter in a semiconductor device includes a first level shifter, a second level shifter, and a first medium-voltage generating circuit. The first level shifter converts a high level of an input signal from a positive first power-supply voltage to a first medium voltage. The second level shifter converts a low level of an output signal of the first level shifter from a third power-supply voltage to a negative fourth power-supply voltage that is lower than the third power-supply voltage. The first medium-voltage generating circuit generates the first medium voltage in such a manner that the first medium voltage is higher than the first power-supply voltage and is lower than a second power-supply voltage, and includes a source-follower NMOS transistor and a clamping PMOS transistor.

Abstract: A receiver includes a positive pulse determination circuit and a negative pulse determination circuit. The positive pulse determination circuit outputs a first L-level between when a pulse signal having a negative amplitude is detected and when neither a pulse signal having a positive amplitude nor a pulse signal having a negative amplitude is detected; otherwise a first H-level if a pulse signal having a positive amplitude is detected during another period. The negative pulse determination circuit outputs a second L-level between when a pulse signal having a positive amplitude is detected and when neither a pulse signal having a positive amplitude nor a pulse signal having a negative amplitude is detected; otherwise a second H-level is output if a pulse signal having a negative amplitude is detected during the other period.
