An approach to implement single-ended power-efficient static class-AB Miller op-amps with symmetrical and significantly enhanced slew-rate accurately controlled output quiescent current is introduced. The proposed op-amp can drive a wide range of resistive capacitive loads. positive negative currents be much higher than the total current. performance achieved by utilizing simple low-power auxil...

Visible light communication (VLC) takes advantage of the widespread use light-emitting diodes (LEDs), and by modifying driver stage, LEDs are capable lighting transmitting information. One main drawbacks is low power efficiency due to modification LED stage in order add capability. Most research work related VLC toward task, whereas there a limited about improvement on efficiency. This article ...

A new design approach for three-stage operational amplifiers (op-amps) is proposed. It allows to actually implement a symmetrical push-pull class-AB amplifier output stage for wellestablished three-stage amplifiers using a feedforward transconductance stage. Compared with the conventional design practice, the proposed approach leads to a significant improvement of the symmetry between the posit...

Compact low-voltage power-efficient operational amplifiers are described that are very suitable as very-largescale-integration library cells because of the small die area of 0.08 mm and the minimum supply voltage of 1.8 V. A key part of the circuit is the rail-to-rail class-AB output stage with folded mesh feedback control that combines power efficiency with operation down to 1.8 V and allows s...
