Voltage Gain Vs Power Gain

Voltage Gain Vs Power Gain. For example, if input power is 0 db and output power is 10 db, the db domain's power gain is 10 db. Three important power gains are operating power gain, transducer power gain and available power gain.

The units v/v are optional but make it clear that this figure is a voltage gain and not a power gain. In this video i have explained why current and voltage gains in decibels are expressed as 20 log of gain and why power gain is expressed as 10 log of gain. Power gain using voltage gain in analog cirucit, people like to use voltage gain but in rf circuit , power gain is more used because people concern more.

It indicates the capacity of a circuit to amplify power with respect to the input power. So, at high gain, you need an input of 1.75v to achieve full output at medium gain you need 2.45 v to achieve full output at low gain you need 5.4v to achieve full output.
