DESIGN METHODOLOGY : Gm over Id Method

All circuits above are designed using Gm over Id Methodology

Simulation Techniques

Throughout the internship, interns will explore various simulation techniques, including DC sweep, transient analysis, and AC analysis, to characterize and analyze the circuit performance.

Software Used

For the implementation and simulation of the tasks, the following software tools will be utilized:

• LTspice: LTspice is a widely used circuit simulation software that allows for the analysis and testing of analog and mixed-signal circuits.

• ADT (Analog Designer Toolbox): ADT is a comprehensive software package specifically designed for analog circuit design. It provides advanced simulation and analysis capabilities for complex analog circuits.

We encourage you to make the most of this internship opportunity, develop your skills in analog circuit design, and gain valuable experience in simulation and analysis.
