Abstract

In this paper, the proposed configuration is realizing High-Pass, Band-Pass, Low-Pass, and Notch filters simultaneously using a single Differential Difference Current Conveyor (DDCC) as an active block. First, the circuit is implemented using passive resistors and then, in proposed configuration, passive resistors are replaced by active resistors. Proposed configuration occupied less area, provide better noise immunity, and offer programmability at the cost of slight increase in Total Harmonic Distortion. The circuit is simulated in cadence virtuoso 180 nm technology and checked for programmability. It is found that cutoff frequency varied from 13.9 to 28.34 MHz by varying the gate voltage from 1.1 to 1.5 V of the active resistance.
