fin = 1 MHz Sine Wave
Adjust fin voltage to obtain 0 dBm at VOS
W Increase fin = frequency until dB meter reads –3dB
RL = 50 , CL = 10 pF
fin = Sine Wave
W Adjust fin voltage to obtain 0 dBm at VIS
fin = 10 kHz, RL = 600 , CL = 50 pF
W fin = 1.0 kHz, RL = 50 , CL = 10 pF
Vin ≤ 1 MHz Square Wave (tr = tf = 2ns)
W Adjust RL at setup so that Is = 0 A
RL = 600 , CL = 50 pF

1. CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating current consumption without load.
Average operating current can be obtained by the equation: ICC(OPR) = CPD VCC fin + ICC. CPD is used to determine the no–load dynamic
power consumption; PD = CPD VCC2 fin + ICC VCC.
