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.
