Rail-to-rail op amps are the perfect fit for applications where the supply voltage range is low and the full dynamic range is necessary at the output
The proposed amplifier has been designed by applying the above-cited AB principle to both the input stage (for increasing dynamically the input source current, see Microelectron. J. 31(3) (1999) 153) and the class-AB output stage (to control and limit the output current). A constant-Gm ...

We have to push gm2 to 2 times of its original value in previous case! It means more power, and might be near the limitation of the process, that is we can only design an amplifier with 50% of the GBW that a specific process permits. Of course, we do not want either of these tw...
Finally, beware the op-amps’ slew rates and if possible, select rail-to-rail op amps to keep the timing reliable. If you want to know all the math behind the circuit so you can adjust different parameters,this documentincludes mathematical explanations so you can try new configuratio...
The power supply units of PCs and other devices incorporate multiple DC power supplies. A power supply line provided by a power supply unit is referred to as a power rail. The entire range from the maximum voltage of a power line (VCC) to its

1. The amplitudes and the phases are heavily dependent upon the applied common-mode input voltage , which is varied from rail ( 1.5 V) to rail (1.5 V) by a step of 0.1 V. This op-amp is unstable and cannot be compensated due to , as we stated in the introduction. In contrast, ...
