Cascading Amplifiers

To process an extremely weak signal, an amplifier must be able to magnify data power by a factor of millions. To achieve this, amplifier stages are frequently connected in series to multiply their gain. Each stage in a chain provides the signal for the following stage, an arrangement called a cascade. The total amplification of a cascade is equal to the product of the individual-stage gains. If each of three amplifiers in cascade has a voltage gain of 100, the overall voltage gain will equal one million. A 10-micro volt signal processed by this cascade increases to a 10-volt signal.
