****************eSim&sky130 circuit design and simulation**********
Title of the project: Audio Power Amplifier
Author: Bhargava Sai Uppala
Audio Power Amplifier is designed as per the reference circuit submitted and simulated using Esim EDA and Skywater PDK.

PROCEDURE:

1.The circuit is built of using 4 NMOS transistors, required capacitors and resistors, dc source and sine wave as input.

2.After building the circuit I just saved my .sch file and verified for errors using ERC marker.As soon as ,there were no errors in my circuit ,I created my netlist(.cir file).

3.Later I converted kicad to Ngspice ,after converting .cir.out file is generated.

4.I opened .cir.out file using notepad and mapped the nmos transistors to sky130 pdk components.

5.Then I gave the appropriate dc value,transient values and sine values.

6.That is it my Input and output waveforms are resulted.


EXPERIENCE:

Yeah,eSim and Skywater pdk are new for me but I just go on learning and implemented in past two weeks.It is pretty interesting participating in such auspicious competitions.

DIFFICULTIES FACED:

1.Faced issues with Ngspice ,but some how went through.

2.Felt difficult while mapping to sky130 pdk


Conclusion:
It is pretty good experience!
