Abstract—This paper presents a low-voltage low-power second generation CCII+ cell using bulk-driven FVF class AB mode operated double recycling current mirror OTA. The OTA is used in the input core of CCII+ cell utilizes bulkcum Quasi Floating Gate (QFG)-based voltage to current converter and Partial Positive Feedback (PPF) to enhance the performance of the circuit. The circuit permits closely railto- rail input common mode range, high output current drive capability with low dual power supply of ± 0.25 V. This circuit produces low input referred noise of 1.65 μV/sqrt Hz, dissipates ultra-low power of 342 nW and is suitable for lowfrequency applications, such as bio-signal processing. Further, to validate this design, a MISO type voltage mode biquadratic filter and voltage mode two phase quadrature oscillator are currently being implemented using this CCII+ cells. The circuit is simulated in tanner EDA tools using 180 nm n-tub CMOS process technology with low bias current of 18 nA.
