Seamos Input Buffer and Seamos Level Conversion Method

摘要

According to the present invention, in a CMOS input buffer for inputting a TTI-level input signal and converting it into an output signal of the SIMOS lever, the control signal has a ground voltage level below the first voltage level of the power supply voltage, and above the first voltage level. The voltage difference is lower than the ground voltage level below the second voltage level of the power supply voltage, and the voltage difference with the power supply voltage decreases gradually as the power supply voltage increases, and the voltage difference with the power supply voltage is always maintained above the second voltage level. And a control signal generation unit for inputting a Ti-Tel level input signal under control of the control signal and generating a CMOS lever output signal. The SiMOS input buffer according to the present invention has the characteristics of resistance to changes in manufacturing process parameters and fluctuations in power supply voltage, improves operation speed, reduces power consumption, and can operate normally even at low power supply voltage. .
