  • Switch circuit using LDMOS device
    Patent number: 9166047
    Abstract: The present invention relates to a switch circuit, and more particularly, to a switch circuit that uses an LDMOS (lateral diffusion metal oxide semiconductor) device inside an IC (Integrated Circuit). In the switch circuit that uses the LDMOS device according to an embodiment of the present invention, a gate-source voltage (VGS) of the LDMOS device may be stably controlled through a current source and resistances, the characteristics of a switch may be maintained regardless of the voltages of both terminals (A and B) by using an N-type LDMOS and a P-type LDMOS in a complementary manner, and the current generated by the current source is offset inside the switch without flowing to the outside of the switch.
