Efficient enhancement/lowering of integrator and differentiator time constants with Fibonacci numbers helping their evaluation

A simple method of efficiently extending or lowering the time constants of a single operational amplifier (OA)RCideal integrator is presented. There exist two schemes in this method both of which require cascading ofR-ladders to a basic integrator block. It is also shown that a consecutive pair of Fibonacci numbers can be effectively used to evaluate the time constant and the gain parameter through a simple rule considerably simplifying the design procedure. Finally, a complementary circuit principle has been used to obtain the differentiators to have similar extention and lowering in time constants.
