62. Multi-Transistor Amplifiers : Cascode Amplifier (Part B)
The chapter discusses the cascode amplifier configuration using MOSFET transistors, explaining how the combination of a common source followed by a common gate enhances voltage gain while maintaining a low input capacitance. The operational principles, biasing requirements, and advantages and disadvantages of this amplifier configuration are analyzed in detail. Emphasis is placed on the comparison between BJT and MOSFET cascode configurations, culminating in the exploration of voltage gain, output impedance, and high-frequency performance.
