Abstract:
A transmission gate comprising: first and second terminals; a first transistor of a first conductivity type which has a drain and source connected between said first and second terminals, and is rendered conductive by a first signal; a second transistor of a second conductivity type which has a drain and source connected between said first and second terminals, and is rendered conductive by a second signal corresponding to an inverted signal of said first signal; a first body effect compensation circuit for reducing the difference between a potential of a back gate and a potential of the source of said first transistor when said first transistor when said first transistor is ON; and a second body effect compensation circuit for connecting the back gate of said first transistor with a back gate of said second transistor directly so as to reduce the difference between a potential of the back gate of said second transistor and a potential of the back gate of said first transistor when said second transistor is ON.
