Realization of Linear and Non-linear circuits with Variable Gain DVCC

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.
