In this paper, a systematic and efficient formulation for analysis of active circuits containing operational transconductance amplifiers (OTA) is presented. The modified nodal approach is used in obtaining the system equations of active circuits. The model of operational transconductance amplifier relating to the used analysis method is given. The model is a matrix-based approach. Thus, it allo...

The general utility of the operational amplifier is derived from the fact that it is intended for use in a feedback loop whose feedback properties determine the feed-forward characteristics of the amplifier and loop combination. To suit it for this usage, the ideal operational amplifier would have infinite input impedance, zero output impedance, infinite gain and an openloop 3 dB point at infin...

An analytical modelling approach for fully differential amplifiers is presented and validated through examples. Separation of the analysis into two steps coupled with linear superposition techniques leads to concise mathematical expressions. An added benefit of the two-step approach is that the usual symmetry assumptions are not needed. As a consequence, the results hold for arbitrary element v...

The idea is using advanced analog design methodology for LVLP to push the basic analog circuit design toward LVLP applications. It is necessary to point out that this report is just an outline of what the final project will accomplish. Those parameters mentioned above are subjected to be changed during the design process to achieve higher performance or more realistic. Parameter Name Value Para...

The current-feedback OTA (CFB OTA) recently appeared in a new classification of operational amplifiers. It is dual to the operational floating amplifier (OFA), so all OFA circuits can readily be transposed into CFB OTA circuits. This paper discusses the theoretical basis of the CFB OTA, shows its relation to the OFA, and compares their performance in a simple V–I converter by showing how both c...

It is accepted that the electromagnetic interference should be addressed with statistical analysis. Usually the impact of electromagnetic interference on different electronic samples is evaluated and the average immunity level is used as a reference. However, this method does not provide enough information to know the probability of failure to the electromagnetic interferences of an electronic ...

In real world signal processing systems, the operational amplifier is the main block for detecting the analog signal. This paper presents a multi optimization technique for the optimal sizing of Transconduc amplifier. By using multiCMOS folded cascode operational transconductance amplifier that operates at low voltage is designed for signal processing application. The MOGWO is a swarm intellige...
