The circuits using current-mode (CM) building blocks have received considerable attention in many filtering and signal processing applications. Compared to their voltage-mode (VM) counterparts, the current-mode building blocks are attractive because of their wider bandwidth, higher slew rate, and lower power consumption. In IC technology, it is desirable to operate circuits at low voltages which can be achieved by using CM building blocks. As a large number of op-amp based circuits with elegant realization procedures are already available, it is worthwhile to convert them into the circuits based on current-mode building blocks. In this paper, a realization of a current mode third order band pass filter is described. The proposed circuit employs an operational amplifier as the basic building unit. The filter circuit realizes quadratic work function. It provides electronically tuning capability of the filter characteristics. The circuit gives better band pass response for 10 kHz≤ f0≤ 70 kHz with better pass band gain, no shift in centre frequency, better symmetry of curves and optimum bandwidth while it has low gain roll-off. The filter circuit is better for wider bandwidth.The circuit is suitable for monolithic integration and high frequency operation. The filter developed have passive sensitivities less than unity in magnitude and active sensitivities one third in magnitude, which is a noteworthy achievement.
