ABSTRACT:
An input circuit of MOS integrated circuit elements for a signal transmitting circuit having a first enhancement-mode MOS field-effect transistor, the gate thereof being connected to a power source and the drain thereof being connected to a first action signal, a second enhancement-mode MOS field-effect transistor, the drain thereof being connected to said power source, and a depletion-mode MOS field-effect transistor, the gate and source thereof being connected to each other, the source of said first enhancement-mode MOS field-effect transistor being connected to the gate of said second enhancement-mode MOS field-effect transistor, the source of said second enhancement-mode MOS field-effect transistor being connected to the drain of said depletion-mode MOS field-effect transistor, the source of the depletion-mode MOS field-effect transistor being connected to the signal transmitting circuit and a boost capacitor being connected between the gate of said second enhancement-mode MOS field-effect transistor and a second action signal to result in a potential at approximately the level of the power source at a node between the second enhancement-mode MOS field-effect transistor and the depletion-mode MOS field-effect transistor.
