Abstract: A high quality factor (Q) 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 (1020 Ω) making it suitable for cascading and dissipates 3.8 mW power. The workability of this circuit has been verified by PSpice simulations using 0.5 mm technology parameters.
