Abstract: A high quality factor (<i>Q</i>) biquad is realized using low-voltage (±0.75 V) second-generation current conveyors (CCII), which can realize dual filter functions (notch/allpass) depending on the resistance ratio. The circuit uses mostly grounded components, thus, enables its easy implementation in standard CMOS technologies. The circuit offers high input resistance (10<sup>20</sup> Ω) making it suitable for cascading and dissipates 3.8 mW power. The workability of this circuit has been<b> </b>verified by PSpice simulations using 0.5 mm technology parameters.
