This repository contains the comprehensive design, analysis, and simulation of a CMOS Differential Amplifier, a core project for the Electronics II course at [Your University Name].
The primary objective was to design a high-performance differential amplifier from the ground up, utilizing MOSFET transistor technology. The project followed a systematic engineering approach:
- Requirement Analysis: Specific design objectives and constraints (such as gain, bandwidth, and power consumption) were analyzed based on provided circuit specifications.
- Theoretical Design: Initial parameter calculation was performed using first-order MOSFET models to determine operating points, bias currents, and transistor dimensions (W/L).
- Circuit Analysis: Theoretical models were rigorously analyzed to predict the amplifier's key characteristics, including differential-mode gain, common-mode rejection ratio (CMRR), and input/output impedances.
- Simulation & Verification: The entire design was simulated and validated using LTspice, verifying the theoretical predictions against detailed transistor-level simulation.
This project is organized into four key phases, each with its dedicated analysis and supporting LTspice simulation files:
- Part 1: Differential amplifier with MOSFET
- Part 2: Active Load
- Part 3: Current Mirror
- Part 4: Self-Biased Differential Amplifier
This systematic modular approach demonstrates a thorough understanding of each facet of analog circuit design.
