Abstract :
A simple rail-to-rail CMOS voltage follower is presented. The proposed circuit is developed based on a conventional class AB voltage follower. The circuit is designed using a 0.5 mum CMOS technology and HSPICE is used to verify the circuit performance. The circuit operates under the supply of plusmn1.5 V. The voltage follower can drive plusmn1.25 V to the 250 Omega with the total harmonic distortion of less than 0.25 % at the operating frequency of 10 KHz. The power dissipation is 3.03 mW
