    In this paper, the circuit-realization of the proportional – integral – derivative – acceleration (PIDA) controller is presented. The circuit is realized with commercially available active components i.e. only four current feedback operational amplifiers (CFOAs) along with passive R and C components. The parameters of the PIDA controller including the proportional gain, the integral time, the derivative time and acceleration gain can be easily adjusted via these resistors and/or capacitors. The proposed PIDA controller offers simple structure with a small number of active elements to be used. The computer simulations results utilizing commercial IC AD844 are demonstrated to confirm the validity of the proposed PIDA controllers.
