    A high performance class AB CMOS rail to rail voltage follower is presented. The circuit is based on the symmetrical class AB voltage follower and can operate under supply voltages of ±1.5 V. The proposed circuit has power dissipation of 2.5 mW under quiescent condition and can drive ±1.2 V to 250 Ω load with a total harmonic distortion of less than 0.6 percent and cut off frequency of 131 MHz. Although simple, the proposed circuit enables the output transistors to drive loads efficiently.

    A ±1.5 V high performance CMOS rail to rail voltage follower is presented. The circuit is based on the symmetrical class AB voltage follower and can operate under supply voltages of 1.5 V. The proposed circuit has power dissipation of 5.2 mW under quiescent condition and can drive ±1.25 V to 250 Ω load with a total harmonic distortion of less than 0.5 percent and cut-off frequency of 237 MHz. Although simple, the proposed circuit enables the output transistors to drive the load efficiently.
