Low-voltage low-power rail-to-rail low-R-x wideband second generation current conveyor and a single resistance-controlled oscillator based on it

This study presents a novel rail-to-rail second generation current conveyor (CCII) based on quasi-floating gate transistors. The circuit operates at very low supply voltage (+/- 0.5 V), dissipates ultra-low standby power (27 mu W), has very high bandwidth (f(-3 dB) of 191 and 181 MHz for A(i) and A(v), respectively) and low input resistance (1.5 Omega). Most favourably, its total harmonic distortion is -69 dB at an input voltage of 99% of power supply and frequency of 100 KHz. HSPICE simulation results confirm the feasibility and the robustness of the presented CCII against process variations (worst-case parameters) and temperature variation. Performance of this CCII is verified using a low-power grounded-capacitor single resistance-controlled oscillator.
