8.1.2 Calculating Output Voltage Swing
This section gives a quick reference of the output voltage swings for different input power levels. In this example, the output is terminated with a 100?Ω differential load and a power gain of 16 dB is assumed.
Figure 8-4 Power and Voltage
LevelsEquation 1. Voltage gain = 20 × log(VO /
VI)
Equation 2. Power gain = 10 ×
log(PO / PI) = 10 × log((VO2 / 100)
/ (VI2 / 50)) = 20 × log(VO / VI) – 3
dB
