66.5.2. Increasing Gain

Try these first

1. 1.

   What does 'active load' refer to in amplification?

   Hint

   Think about what replaces traditional resistive components in amplifiers.

2. 2.

   Why do passive loads limit voltage gain?

   Hint

   Consider the characteristics of resistors in an amplifier circuit.

3. 3.

   What is an active load?

   • A passive resistor
   • A transistor used in amplification
   • None of the above

   Hint

   Think about the role of transistors in amplifying signals.

4. 4.

   True or False: Passive loads can achieve higher voltage gain than active loads.

   • True
   • False

   Hint

   Refer to the definitions and characteristics of passive versus active components.

5. 5.

   Design an amplifier circuit with an active load configuration, calculating gain and efficiency using specified values for g_m and R.

   Hint

   Consider how the active load can affect your gain calculations versus using passive components.

6. 6.

   Analyze the thermal impact of an amplifier circuit utilizing high transconductance. What changes should be anticipated in heat management?

   Hint

   Think of practical applications in circuits where heat dissipation management is crucial.
