Reference of Current Source
An external decoupling capacitor
is placed between this pin and
ground. An external resistor from
this pin to ground can controls the
reference current of current
source and the related
performances, such as NF and
gain.
Supply Voltage
ESD protection transistor exists
between V+ and ground.
