AN INVESTIGATING ON CDBA BASED CONTINOUS TIME CIRCUITS

Abstract

Over the year of time, the evolution of modern application of signal processing has followed the trends of so called current mode, when signals, representing the information being processed, are in the form of current. In contrast to the conventional mode which utilized electric voltage, the current mode circuit can exhibit higher bandwidth, better signal linearity, higher slew rate and lower power consumption. Since they are designed for lower voltage swings, smaller supply voltage can be used. The current differencing buffered (CDBA) amplifier can operate in both current mode and voltage mode, which provides flexibility. This project discusses implementation of lossless grounded negative inductor circuits (and application thereof), and oscillator circuit, using single CDBA. CDBA is designed using AD844 IC.
