16. An apparatus, comprising:
an amplifier comprising a first input stage and a second input stage, wherein the first input stage comprises:
a first transistor of a first type coupled with a first node and having a gate coupled with a first signal;
a second transistor of a second type coupled with the first node and having a gate coupled with the first signal;
a first switch coupled with the first transistor and a second node and configured to receive a first control signal; and
a second switch coupled with the second transistor and the second node and configured to receive a second control signal, wherein the first input stage of the amplifier is configured to switch between the first transistor of the first type being activated and the second transistor of the second type being activated, wherein the first transistor of the first type is configured to be activated based at least in part on the first switch receiving the first control signal and the first signal having a first voltage profile over a range of a condition, and wherein the second transistor of the second type is configured to be activated based at least in part on the second switch receiving the second control signal and the first signal having a second voltage profile over the range of the condition.
