Abstract
La invención se refiere a un interruptor analógico formado sobre un sustrato semiconductor, que comprende puertos de entrada y salida (204, 205), y un primer transistor MOS en modalidad mejorada (201), formado en un hueco aislado en el material del sustrato, y que tiene su puerto (G) conectado para recibir una señal de control (207); y que tiene un extremo (S) de su canal conductor y su hueco (W) conectados al puerto de entrada (204). Un segundo transistor MOS en modalidad mejorada (202) se forma en un hueco aislado en el sustrato, y tiene un extremo (S) de su canal conductor y su hueco (W) conectados al puerto de entrada (204), y tiene su puerto (G) conectado al otro extremo (D) del canal conductor del primer transistor (201). Un tercer transistor MOS en modalidad mejorada (203) se forma en un hueco aislado en el sustrato, y tiene su puerto (G) conectado para recibir el complemento (208) de dicha señal de control, y tiene su canal conductor (D, S) conectado entre el puerto de salida (205)y el otro extremo (D) del canal conductor del segundo transistor (202), y tiene su hueco (W) conectado a una de las líneas de alimentación (OV) del interruptor. Los medios de control (210) están conectados al puerto (G) del segundo transistor (202) para mantener al segundo transistor (202) en un estado opuesto al del primer transistor (201).
