Abstract
A voltage dividing circuit comprises a plurality of series-connected insulated-gate FETs, each having its gate and drain short-circuited with each other and its source and substrate short-circuited with each other. A substrate in which one FET is formed is isolated from another substrate in which another FET is formed.
