Title: Design of IC 741 tester circuit
This circuit is designed in Esim and simulated using ngspice,sky130
This whole ciruit is designed using nmos,pmos,resistor's & capacitor's

Procedure:
1) First design the circuit in Esim using nmos,pmos,resistor's & capacitor's
2) Then generate the netlist in Esim
3) Modify the pmos and nmos using sky 130 technology
4) Then save the file as .cir where sky 130 folder present
5) Now simulate the circuit using Ng spice

Output:
1) When pulse or sin is given,getting same input as output
2) when dc value is given there is negligible transition in the ouput
