Abstract

The invention provides a driving circuit for an input / output port, which comprises a main output stage and an enhancing unit, wherein the main output stage is used for receiving at least one driving signal and outputting an output signal corresponding to an input signal based on the driving signal, and the enhancing unit is coupled with the main output stage and is used for receiving and detecting the electrical level of the output signal, thereby maintaining or enhancing the output thrust of the main output stage.

Description

technical field [0001] The present invention relates to a driving circuit, and in particular to a driving circuit of an input / output interface. Background technique [0002] Generally speaking, when a digital signal is transmitted through a driving circuit (that is, an input / output interface (I / O)) in an integrated circuit (IC), in order to increase the transmission speed, the driving of the driving circuit must be increased. capacity (that is, the output thrust of I / O), but in the case of increasing the driving capacity, it is bound to face the situation of over damping of the output signal, such as Image 6 as shown. Such jitter will not only become power noise to interfere with the system power supply, but will also be emitted in the form of electromagnetic disturbance (EMI), resulting in product specifications not meeting safety standards. [0003] Traditionally, the problem of overshoot jitter caused by the increase of the driving capability of the output signal can be...
