Realization of variable Q bandpass filter using low-voltage CCII

Susheel Sharma, Seema Rana, Kunal Pal

Abstract

A voltage-mode bandpass filter with variable Q, realized using a single FGMOS based second generation current conveyor (CCII) that operates with ± 0.75 V supply voltage, has been presented. The Q and pass band gain (K) can be adjusted for desired values within some limits by selecting the various passive components used in the circuit. The workability of this circuit has been verified by PSpice simulations using 0.5 μm technology parameters.
