2: hw06b.py solving simultaneous equations using sympy Given the following 3 simultaneous current equations for this transistor circuit, solve for id, Vo and Vs ID=Kn(VDDVaVTN)2(1+(VDDVd))ID=Kn(VDViVTN)2(1+(VsVD))ID=Kn(VsVTN)2(1+Vs) 1. A: write a function solve(Kn, VDD, Vg, Vtn, lambda) which returns (Id, Vo, Vs) as a tuple. a. It should default Vtn =1 and lambda =0 if they are not given. b. Since it is a polynomial function it will have many solutions. Some will be complex some will be real, but invalid, but only one should solve the circuit. Use a for loop to go through the solutions returned by sym. solve and only return teh valid one. i. Make sure it only returns real valued answers. Sometimes the value will be reported as complex due to rounding errors even though it is real. So if it is complex look at the imaginary part and see if it is negligibly smanl (1+j1e25) is actually real ii. Verify that the answers are valid for the given problern. 1. Since this circuit has no negative supply, Vs, Vo and Ig must be positive. 2. Since this circuit is powered by a DC supply = VCC, no voltages can be above VCC iii. If no solution is found it should raise a ValueError exception. 2. Include a main function that takes Kn Vdd VgVtn and Lambda as command line arguments and prints the answer as a. "Id=\{:.2e\} Vo=\{:2e\} Vs={:2e} b. If no valid solution is found, then main program should print "No solution found" and return 1 c. For example: Sw06b.py 1e-3 5310.1 i. Should print "ld=2.94e-04 Vom3.49e+00 Vsa-1.51e+00
