According to one embodiment, a CMOS input stage circuit provided herein may generally include a pair of NMOS input transistors (N1, N2), a first pair of PMOS input transistors (P1, P2), a first current source, a current steering circuit and a current stealing circuit. Differential input voltages may be supplied to gate terminals of the pair of NMOS input transistors (N1, N2) and the first pair of PMOS input transistors (P1, P2). The first current source may be coupled to source terminals of the first pair of PMOS input transistors (P1, P2) and may be configured to generate a first current. The current steering circuit may be configured to steer the first current to the pair of NMOS input transistors (N1, N2) and/or to the first pair of PMOS input transistors (P1, P2), depending on whether a common-mode input voltage is significantly greater than, significantly less than or substantially equal to a cross-over voltage. The current stealing circuit may be configured to steal a portion of the first current, so that a smaller remaining portion of the first current is divided among the pair of NMOS input transistors (N1, N2) and to the first pair of PMOS input transistors (P1, P2) when the common-mode input voltage is substantially equal to the cross-over voltage.
