The invention relates to a rapid charging and discharging circuit of a switch. The rapid charging and discharging circuit comprises a quick charging and discharging module, a receiving end switch anda transmitting end switch; the transmitting end switch is connected with the transmitting end; the receiving end switch is connected with the receiving end, the transmitting end switch and the receiving end switch are jointly output to the antenna end, control signals of the transmitting end switch comprise a signal cr _ p and a signal cr _ n which are opposite to each other, control signals of the receiving end switch comprise a signal cr _ n and a signal vg1, and the signal vg1 is connected with the rapid charging and discharging module. According to the technology provided by the invention,through feedback of the voltage at the control end of the switching tube, high-voltage control on the rapid charging and discharging path is achieved under the condition of ensuring the safety of thedevice, so that the original charging speed can still be kept along with the rise of the control voltage.
Description
technical field [0001] The invention relates to the technical field of integrated circuit design and manufacture, in particular to a fast charging and discharging circuit of a switch. Background technique [0002] With the rapid development of communication systems, the requirements for switching speed of switches in chip design circuits are getting higher and higher. The switch in the chip generally includes a transmitting end, a receiving end and an antenna end. The transmitting end and the receiving end generally use a switch tube. The transmitting end is controlled by the control signal inside the chip, and the receiving end is controlled by an external signal or a radio frequency signal inside the chip. The switching speed of the switch is limited by the charging and discharging time of the control terminal of the switching tube. In the traditional switch design, the charging and discharging time is limited by the large resistance at the control terminal and the size o...
