A driving voltage output circuit for a matrix display panel includes high-side voltage followers and low-side voltage followers. Each voltage follower includes a differential input stage, a control stage, and an output stage. First and second transistors in the differential input stage receive non-inverting and inverting inputs and produce first and second potentials that control the control stage. Third and fourth transistors of different channel types in the control stage are connected in a push-pull configuration between high-side and low-side power supply potentials to generate a control potential. Fifth and sixth transistors of identical channel types in the output stage are connected in series between an intermediate reference potential and one of the power supply potentials, and are controlled by the first potential and the control potential to generate an output potential. The output potential is fed back as the inverting input. |
