CCCDBA Based Voltage Mode Differentiator and Integrator for Integrated Chips

In the present paper a voltage mode differentiator (First order high pass filter) and voltage mode integrator (First order low pass filter) have been proposed by using current-controlled current differencing buffered amplifier (CCCDBA). In the present work, an effort has been made to control the first order filters parameters electronically, adjusting bias current of CCCDBA. Here, in each circuit only one CCCDBA and a grounded capacitor without external resistor have been utilized. The designed circuits are very suitable for integrated circuit and very easy in implementation. The circuits’ performance is simulated through PSPICE and its simulated results obtained so is comparable to the theoretical one. The circuits operate over a frequency range of few megahertz.
