Term: Current Mirror
Definition: A current mirror is a circuit that copies (mirrors) a current flowing in one active device by controlling the current in another active device, ensuring consistent current levels in various applications.
Term: Small Signal Model
Definition: A small signal model is a linear approximation used for circuit analysis under the assumption that signals of interest are small perturbations around a DC operating point.
Term: Operational Amplifiers
Definition: Operational amplifiers are high-gain voltage amplifiers with differential inputs and a single-ended output, widely used in signal conditioning, filtering, and mathematical operations.
