In this brief, the existing integrators/differentiators have been discussed along with the methods to arrive at the same. Using those methods, few new Integrators/Differentiators have been designed. The methods include Linear Interpolation and Linear optimization. Secondly, Simulated Annealing Algorithm has been applied for further optimization and subsequent design of wideband integrators/ differentiators. The Energy function that would help in minimization of error has also been discussed.
