The chapter discusses the application of current mirrors in various amplifier configurations, including Common Collector, Common Drain, and Differential Amplifiers. It elaborates on the current mirror's role in improving performance metrics such as common mode and differential mode gains, highlighting the underlying principles and equations that govern transistor behavior in these circuits.
A current mirror is a circuit configuration that replicates a current through one active device by controlling the current through another active device in a circuit, ensuring precise current management.
Common mode gain is the amplification of signals that are common to both input terminals of a differential amplifier; it is often minimized to improve differential performance.
Differential mode gain represents the amplification of the difference between two input signals in a differential amplifier, enhancing the desired signal while reducing common noise.
