Patent ID: 7960952

Claim:
A switch comprising: a first transistor; a plurality of second transistors, each having a first node coupled to a first node of the first transistor; a first resistor with one terminal coupled to a second node of the first transistor and with the other terminal coupled to a first power source for supplying a first voltage, wherein a first current, which is the sum of currents flowing to the plurality of second transistors, sequentially changes from a time point at which the first transistor is turned on; wherein a distance between a second power source for supplying a second voltage to a second node of each of the plurality of second transistors and the second node of each of the plurality of second transistors is not uniform; wherein when the plurality of second transistors is turned on, the plurality of second transistors is sequentially turned on starting from the second node of the plurality of second transistors closest to the second power source.
