The analog circuits are two types; linear and non-linear. The analog circuits are, might be, with or without feedback. In general, linear circuits need negative feedback while negative or positive feedback needed in non-linear circuits. Here, the VG-DVCC is proposed for the realization of linear and non-linear circuits. Basically, this VG-DVCC is a low-gain active network block. Thus, feedback is not needed for the realization of linear circuits whereas non-linear circuits needed feedback. This paper highlights the realization of linear circuits: Instrumentation Amplifiers, Active Filters, and nonlinear circuits: Schmitt Trigger comparator, Square wave generator with variable gain differential voltage current conveyor. The performance is validated by simulation using ADS.

Schmitt trigger is designed using the single second generation Current Controlled Conveyor. The proposed configuration utilizes single CCCII and only two externally connected resistors and is able to produce dual output square wave signal. The topology has the benefit of having a simple circuit, offering a large bandwidth and improved slew rate. PSPICE simulator using OrCad 16.3 version, 0.35 μm CMOS technology is used to verify the design, hysteresis is determined and compared with the existing methods available in the literature. The proposed configuration is tested using the experimental setup involving CFOA (AD844AN) and OTA (LM13700). The results have been found satisfactory in both simulation and experimental aspect. Montecarlo analysis and orstcase analysis are determined to prove the circuit efficiency in terms of critical parameters such as resistance with a tolerance of 5%. The hysteresis is also determined, that can reduce the effect of noise, able to produce exact square wave at the output. Schmitt trigger circuits find the applications in the field of Bio medical applications, analog signal processing, communication systems, waveform generators, pulse width modulators, multivibrators, flip-flops and in many other amplifier circuits. The basic application of Schmitt trigger is a square wave generator. The proposed topology is the best suited for monolithic IC fabrication.

Abstract This work presents a wide-band active filter for RF receiver. The design uses Carbon Nanotube-FET (CNFET) based differential voltage current conveyor (DVCC) for the implementation of the proposed filter. The filter is designed to operate Ku-band frequencies (12-18 GHz), which is used in satellite communication. Additionally, CMOS based circuit and CNFET-based circuit for DVCC are compared for the performance evaluation. HSPICE simulations have been carried out to test the design aspects of the circuit. The CNFET-based circuit has better results in terms of 60 % reduction in the power consumption and about six times improvement in the bandwidth. The filter utilizes low supply voltage of 0.9 V and consumes 524 µW only. The proposed filter outperforms the existing CMOS-based designs which suggests its usage for low-power high-frequency analog circuits.
