An amplifier circuit having a limit function for the output lower limit value and a complementary amplifier circuit (AMPLIFIER CIRCUIT AND COMPLEMENTARY AMPLIFIER CIRCUIT WITH LIMITING FUNCTION FOR OUTPUT LOWER LIMIT)

摘要

Quot; H " level by the P-channel MOS transistor 104 rendered conductive by the precharge signal, and the output potential level of the differential amplifier circuit 102, which outputs the corresponding signal, The data propagation time is not driven by the differential amplification circuit 102 until the difference between the potential level of the line ("H" level) becomes the threshold voltage Vth (n) of the N-channel MOS transistor 106.;By doing so, there is an effect that incorrect data is not output to the data line due to the lack of equalization of the I / O line pair or the presence of the offset of the differential amplification circuit 102.
