Tóm tắt
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 /spl plusmn/1.5 V. The proposed circuit has power dissipation of 2.5 mW under quiescent condition and can drive /spl plusmn/1.2 V to 250 /spl Omega/ 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.
