Low-voltage low-power rail-to-rail low-Rx 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±±W), has very high bandwidth ( f -3-dB of 191 and 181 MHz for Ai and Av , respectively) and low input resistance (1.5 ). 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.
