Embodiment 1

[0028] The invention provides a self-induction and self-acceleration bidirectional level conversion circuit. By setting a self-acceleration module, the port voltage is pulled up transiently and quickly to achieve rapid level conversion; the built-in direction self-induction module can allow the device to sense and control the direction of data flow without the need for a direction control pin; not only can it convert between specific dual power supply voltages, but it also has a relatively wide voltage conversion range; it can not only convert from low voltage to high voltage, but also Convert from high voltage to low voltage.

[0029] Such as figure 2 As shown, the self-induction self-acceleration bidirectional level conversion circuit includes a self-acceleration module, a direction self-induction module, a transmission tube, a pull-up path and a grid voltage VG generation circuit. The self-acceleration module pulls up the port voltage transiently and quickly to realize fa...

Abstract

The invention discloses a self-induction and self-acceleration bidirectional level conversion circuit, and belongs to the technical field of electronic circuits. The circuit is simple in structure, good in working performance, high in conversion speed and higher in working frequency under the common CMOS process; not only can conversion be carried out between specific double-path power supply voltages, but also a relatively wide voltage conversion range is achieved; and an independent direction control bidirectional conversion function is built in, so that the device can sense and control thedata flow direction, and a direction control pin is not needed. Not only can a low voltage be converted into a high voltage, but also the high voltage can be converted into the low voltage. Digital level conversion and matching work among most of current systems can be well completed. The circuit is less affected by temperature, power supply voltage and process. Therefore, the self-induction and self-acceleration bidirectional level conversion circuit applied to the field of signal transmission provided by the invention can greatly improve the level conversion efficiency, and has an importantapplication value.

Description

technical field [0001] The invention relates to the technical field of electronic circuits, in particular to a self-induction self-acceleration bidirectional level conversion circuit. Background technique [0002] As modern electronic systems run faster and faster, and the amount of data processed in parallel increases, in order to reduce the power consumption of core processors, a large number of core processor systems powered by low voltage have been produced. To transmit information between systems using two different logic standards, it is necessary to use corresponding logic level conversion circuits to realize data conversion between chips with different supply voltages. [0003] A traditional level shifter circuit such as figure 1 Shown, input in, its high level is vdd, output out, its high level is vdda. When the input in changes from vss to vdd, the MOS tubes MN1 and MP2 are turned on, the MOS tubes MN2 and MP1 are turned off, and the output level is pulled up to ...
