Problems solved by technology

In addition, since the maximum voltage withstood by the NMOS transistors NG1 and NG2 is about 2.5 volts, their gates need to be made thicker, so their threshold voltages are also higher.
At this time, the lower input voltage Vin cannot turn on the NMOS transistors NG1 and NG2, so the switching speed of the NMOS transistors NG1 and NG2 is slow

Description

technical field [0001] The invention belongs to the field of digital-analog hybrid integrated circuits, and relates to a voltage level conversion circuit, in particular to a level conversion circuit composed of a monostable pulse delay circuit, a current comparator and an inverter, which is suitable for use in integrated circuits Conversion between different digital signal levels. Background technique [0002] When the control signal is transmitted from one working voltage circuit part to another working voltage circuit part in the integrated circuit, due to the difference in working voltage, it is necessary to perform level conversion on the transmission signal. Especially in high-frequency signal circuits, when the voltage difference is large, the level conversion processing of the transmission signal is very important. As shown in Figure 1, this is a traditional voltage level shifter for converting the existing low voltage level to high voltage level, which includes PMOS...
