Abstract
ting conditions. Consider the operation of the PLDO as
an example. When the differential input is positive but the
amplitude is low, the PLDO tends to regulate its outputVDD_AB
to a voltage lower than VDDL. However, due to the presence
of the diode DP, VDD_AB is clamped to VDDL minus the diode
drop. As a result, the input pair of EA P experiences a large
voltage difference and turns off the transistor MP, redirecting
the current in AB-LA to flow from VDDL via DP rather than
from VDDH. When the d
