    Any paper about low voltage input diff pair used in the high volage amp?

    Any papers about this issue:
    high supply voltage but low voltage input diff pair is used in order to reduce size and to improve the matching issue.
    Thanks.

    Seems to me that it's possible to position I/O at any level between the supply rails, even with a high supply voltage. Nevertheless you must consider power dissipation of components which drop greater watts, the higher the voltage.
