ABSTRACT:
A rail-to-rail operational amplifier is provided with a high-side current adjusting circuit and a low-side current adjusting circuit. On a basis of a comparison between a first input voltage and a second input voltage, the high-side current adjusting circuit adjusts a high-side bias current. Under a condition that the first input voltage is smaller than the second input voltage, the high-side current adjusting circuit increases the high-side bias current when an absolute value of a difference between the first and the second voltages increases. On a basis of the comparison between the first and the second input voltages, the low-side current adjusting circuit adjusts a low-side bias current. Under a condition that the first input voltage is larger than the second input voltage, the low-side current adjusting circuit increases the low-side bias current when the absolute value of the difference between the first and the second voltages increases.
