Key Concepts

Voltage Gain

Voltage gain is the ratio of the output voltage to the input voltage within an amplifier or any electronic stage. It characterizes how much an amplifier increases the strength of a signal, serving as a fundamental measure in the analysis of electronic circuits.

Decibels

Decibels (dB) are a logarithmic unit used to express ratios, such as voltage gain, in a way that can conveniently handle large ranges of values. In the context of voltage gains, the conversion typically uses the formula 20 log??(V_out/V_in), making multiplicative gains additive when working in dB.

Multi-stage Amplifiers

Multi-stage amplifiers consist of several amplifier stages cascaded together, where the overall gain is the product of the gain of each stage. When expressing these gains in decibels, the additive property of the dB scale simplifies the computation of the total gain by summing the decibel values of individual stages.
