Embodiment Construction

[0020] Embodiments will be described below with reference to the drawings.

[0021] figure 1 It is a configuration diagram showing an example of a configuration of a switching device including a switching circuit according to an embodiment.

[0022] The switching device 1 includes a switching circuit 10 , a transmitting and receiving circuit 11 , and a control circuit 12 . Furthermore, the switching device 1 is connected to the antenna ANT. The control circuit 12 is connected to the switch circuit 10 and the transceiver circuit 11 . The control circuit 12 controls the switch circuit 10 and the transmission and reception circuit 11, thereby controlling the transmission and reception of a high-frequency signal (hereinafter referred to as an RF signal). Thus, the switch device 1 can perform transmission and reception of RF signals and the like.

[0023] The control circuit 12 outputs a control signal CTRL described later to the switch circuit 10 . Switching of the switch cir...

Abstract

A switching circuit includes a high-frequency switch, a first charge pump circuit, a boost signal generating circuit, and a second charge pump circuit. The high-frequency switch switches transmission and reception of the high-frequency signal. The first charge pump circuit generates a first voltage and a second voltage supplied to the high-frequency switch. The boost signal generation circuit generates a first boost signal for temporarily improving a driving capability of the first charge pump circuit when an edge of the input signal is detected. The second charge pump circuit operates to temporarily improve the driving capability of the first charge pump circuit when the first boost signal is input.

Description

[0001] related application [0002] This application enjoys the priority of the basic application based on Japanese Patent Application No. 2020-159604 (filing date: September 24, 2020). This application incorporates the entire content of the basic application by referring to this basic application. technical field [0003] Embodiments of the present invention relate to a switching circuit. Background technique [0004] High-frequency switches (hereinafter referred to as RF switches) are used in mobile phone base stations and the like to switch on / off (switching for transmission and reception), impedance adjustment, and frequency band change when transmitting and receiving wireless signals. [0005] RF switches are used in base stations of mobile phones, etc., and thus require higher withstand voltage and faster switching time of the switch, but there is a problem that it is difficult to achieve both high withstand voltage and faster switching time of the switch.
