1. A rail-to-rail (R-R) input stage circuit operating over a rail-to-rail input common mode voltage range, comprising:

  • a differential pair circuit, having a first input common mode voltage range, coupled to a level shifted differential pair, having a second input common mode voltage range to enable operation of the R-R input stage circuit over an input common mode voltage that extends from a negative power supply to a positive power supply; and

    a first bias control circuit, coupled to the level shifted differential pair, to dynamically control the bias current of the level shifted differential pair when the input common mode voltage of the R-R input stage circuit is outside the second input common voltage range.
