Current Differencing Transconductance Amplifier And Its Applications : LAP Lambert Academic Publishing : 9786200211392 : 6200211396 : 11 Jun 2019 : Presently there is a growing interest in synthesizing current-mode circuits because of their potential advantages such as larger dynamic range, higher signal bandwidth, greater linearity, simpler circuitry, and low power consumption. In the proposed square-triangular waveform generator circuits, it has better high frequency and less number of passive elements compared to conventional circuits. The performance of CDTA based Schmitt trigger circuits and square-triangular waveform generator circuits are examined using Cadence and the model parameters of a gpdk 180 nm technology. The mathematical expressions obtained for the proposed circuits have been verified with Cadence simulation. Later, the two square-triangular waveform generator circuits were built using commercially available Current Feedback Operational Amplifier (AD844 AN) and Operat
