This article given a second generation current controlled current conveyor positive (CCCII+), second generation current controlled current conveyor negative (CCCII-), Quadrature oscillator with high-Q frequency choosing network and implementing completely different phase oscillators by employing (CCCII+) positive and (CCCII-) negative, and high band pass filter network, the approach is predicted on the CMOS technology . The root of this concept is, considering a customary voltage mode oscillator which consists of band pass filter with prime quality issue (high-Q) and voltage mode amplifier is transfigure into current mode oscillator by replacing tans-conductance amplifier. Because the loop of the oscillator is has lavish selectivity, the oscillator process less distortion. In addition 3dB bandwidth, oscillating condition, oscillation frequency of the oscillator could linearly, independently and electronically be tuned by adjusting the bias current of the (CCCII±)[1], lastly different simulations have been carried out to verify the linearity between output and input ports, range of frequency operations. These results can justify that the designed circuits are workable.

Simulation Results

A new current-mode band-pass filter using the inverting second-generation current conveyor (ICCII) is introduced. The circuit is generated from a frequency-dependent negative resistance (FDNR)-C circuit realized using ICCII+. It is observed that a voltage-mode band-pass filter using two CCII+ has similar transfer function to this current-mode filter. The adjoint network theorem is used to demonstrate the transformation between the two circuits. Two new voltage-mode grounded capacitor band-pass filters using two ICCII are also introduced. The first voltage-mode circuit is generated from the FDNR-C circuit and employs two opposite Z polarity ICCII. The second voltage-mode circuit is obtained from the first circuit by relocation of the input and a grounded terminal. Two new additional grounded capacitor and grounded resistor current-mode band-pass filters with independent control on the filter Q are also introduced. Spice simulation results with 0.35 μm CMOS transistors model are included to demonstrate the practicality of the two ICCII- band-pass current-mode filter.

In this paper, we introduce an implementation of a CCII-based grounded inductance operating in class AB. In order to get tunable characteristics of the design, a translinear CCII configuration is used as a basic block for its high level of controllability. A frequency characterization of the translinear CCII is done. In order to optimize its static and dynamic characteristics, an algorithmic driven methodology is developed ending to the optimal transistor geometries. The optimized CCII has a current bandwidth of 1.28 GHz and a voltage bandwidth of 5.48 GHz. It is applied in the simulated inductance design. We first consider the conventional topology of the grounded inductance based on the generalized impedance converter principle. Making use of the controllable series parasitic resistance at port X in translinear CCII, we design tunable characteristics of the inductance. The effect of current conveyor's nonidealities has been taken into account. A compensation strategy has been presented. It is based on the insertion of a high active CCII-based negative resistance and a very low passive resistance. The compensation strategy does not affect the inductance tuning process. Simulation results show that the proposed inductance can be tuned in the range [0.025 μH; 15.4 μH]. The simulated inductance has been applied in a fully integrated tunable high frequency band pass filter to illustrate the versatility of the circuit. The filter is electrically tunable by controlling the conveyor's bias current.
