  • Patent number: 11146259
    Abstract: A voltage equalization method for use in a radiofrequency switch having multiple transistors connected in series and the radiofrequency switch. In the voltage equalization method, capacitors are additionally provided as parasitic capacitances between source electrodes and drain electrodes of transistors (M1-MN) connected in series to compose a radiofrequency switch, and voltage drop uniformity is implemented for the transistors (M1-MN) by adjusting the parasitic capacitances of the transistors (M1-MN). By means of different combinations of the positions, sizes, and spacing of metal bars on a first metal layer (1) and on a second metal layer (2), the parasitic capacitances between the source electrodes and the drain electrodes of the transistors (M1-MN) can be finely adjusted, thus increasing the voltage drop uniformity of the transistors (M1-MN). The method uses less transistors to accomplish the design of the radiofrequency switch.
