(a) We have talked about the depletion capacitance. There is also something called the diffusion capacitance in a diode. This comes from the buildup of minority carriers when the diode is forward biased. Using the definition of capacitance, the minority carrier lifetime, the diffusion length, the equation for excess minority carrier concentration at the depletion region edges, and the minority carrier diffusion equation, derive a simple functional form for this "Diffusion Capacitance". (b)Using your derived equation, how can we make the diffusion capacitance smaller? (c)Will the diffusion capacitance cause a problem if we want to make a very high speed diode?

his exercise examines the single error correcting, double error detecting (SEC/DED) Hamming code. [5] Section 5.5 states that modern server memory modules (DIMMs) employ SEC/DED ECC to protect each 64 bits with 8 parity bits. Compute the cost/performance ratio of this code to the code from Exercise 5.14.1. In this case, cost is the relative number of parity bits needed while performance is the relative number of errors that can be corrected. Which is better?

Consider a mild steel specimen with yield strength of 43.5 ksi and Young's modulus of 29,000 ksi. It is stretched up to a point where the strain in the specimen is 0.2% (or 0.002). If the specimen is unloaded (i.e. load reduces to zero), the residual strain (or permanent set) is: 0.05% 0.1% 0% 0.2%

Write a C program called threadcircuit to run on ocelot which will provide a multithreaded solution to the circuit-satisfiability problem which will compute for what combinations of input values will the circuit output the value 1. This is the sequential solution, which is also attached. You should create 6 threads and divide the 65,536 test cases among them. For example, if p=6, each thread would be responsible for roughly 65,536/6 number of iterations (if it's not divisible, some threads can end up with one more iteration than the others). The test cases must be allocated in a cyclic fashion one by one.If a thread finds a combination that satisfies the circuit, it should print out the combination (like in the given sequential version), along with the thread id (a number between 0 and 5 (p-1)). In the end, the main thread should print out the total number of combinations that satisfy this circuit (like in the given sequential program). Mutex should be used to update the total by each thread. An example output of the program is shown below:OUTPUT EXAMPLE:% threadcircuit0) 01101111100110010) 11101111110110012) 10101111100110011) 11101111100110011) 10101111110110011) 01101111101110010) 10101111101110012) 01101111110110012) 1110111110111001There are 9 solutionsCODE TO USE:#include #include /* Return 1 if 'i'th bit of 'n' is 1; 0 otherwise */#define EXTRACT_BIT(n,i) ((n&(1
