OTAs - based Positive / Negative Floating Inductance Simulator

This paper presents a method to realize floating inductance simulator using Operational Transconductance Amplifiers (OTAs). Both positive and negative floating inductances can be achieved without changing the circuit topology. The realization method is based on the use of commercially available OTAs and a grounded capacitor. The proposed circuit is attractive in terms of simple configuration an...

A Nonlinear Macromodel for CMOS OTAs

A nonlinear parameterizable macromodel fo r CMOS Operational Transconductance Amplijiers (OTAs) is presented. The macromodel captures the DC, AC and large signal features of the transistor level original circuit, thus modeling accurately its time domain and nonlinear performance. The main contribution of this work is to account for the bias-dependent transconductance nonlinearities in the circu...

New Proposed Second-Order ASDM Using OTAs

In this work, we present a new proposal for the second-order Adaptive Sigma Delta Modulation (ASDM). The new proposed Adaptation scheme is based on using Operational Transconductance Amplifier (OTAs) as an Integrator and as an Amplifier to adapt the quantizer stepsize to control the voltage gain by feedback the quantizer output through adaptation scheme. The stepsize is changing up or down by t...
