Abstract
A low voltage two stage operational amplifier with class AB output stage is presented, featuring simplicity and efficiency. It has a large effective output current boosting factor (~50) and close to a factor 2 bandwidth enhancement. This is achieved at the expense of minimum additional circuitry with no extra static power dissipation. Experimental verification of the characteristics of the proposed circuit is provided
