This paper deals with well-defined design criteria for two-stage CMOS transconductance operational amplifiers. A novel and simple design procedure is presented, which allows electrical parameters to be univocally related to the value of each circuit element and biasing value. Unlike previous methods, the proposed one is suited for a pencil-and-paper design and yields accurate performance optimi...

The subject of the study is design of multi-valued (analog) CMOS fuzzy controllers. A functional completeness of summing amplifier with saturation in a multivalued logic of an arbitrary value proven in previous works gives a theoretical background for analog implementation of fuzzy devices. Compared with the traditional approach based on explicit fuzzification / defuzzification procedures analo...

DESIGN AND IMPLEMENTATION OF A FOUR TERMINAL FLOATING AMPLIFIER AND ITS APPLICATION IN ANALOG ELECTRONICS By José A. García Rivera The field of analog electronics has developed and matured for the past two decades. Within this field, design of analog amplifiers has received attention due to changes in technology. Amplifier circuits, considered analog devices, are found anywhere in many house el...

A parallel (2, n – 2)-system is investigated here where two units start their operation simultaneously and any one of them is replaced instantaneously upon its failure by one of the (2; n – 2) warm standbys. We assume availability of n non-identical, non-repairable units. The unit-lifetimes in full operational mode and in partial operational mode have general distribution functions Gi and Hi (i...

A new approach for CMOS op-amp circuit synthesis has proposed here. The approach is based on the observation that the rst order behavior of a MOS transistor in the saturation region is such that the cost and the constraint functions for this optimization problem can be modeled as convex functions. Second order e ects are then handled by formulating the problem as one of solving a sequence of co...

A novel low-voltage two-stage operational amplifier employing resistive biasing is presented. This amplifier implements neutralization and correction common mode stability in second stage while employs capacitive dc level shifter and coupling between two stages. The structure reduces the power consumption and increases output voltage swing. The compensation is performed by simple miller method....

This paper presents and experimentally verifies an optimized design procedure for a CMOS low noise operational amplifier. The design procedure focuses on the noise performance, which is the key requirement for low noise operational amplifiers. Based on the noise level and other specifications such as bandwidth, signal swing, slew rate, and power consumption, the device sizes and the biasing con...

A structural operational semantics of a non trivial sublan-guage of Java is presented. This language includes dynamic creation of objects, blocks, and synchronization of threads. First we introduce a simple operational description of the sequential part of the language, where the memory is treated as an algebra with suitably axiomatized operations. Then, the interaction between threads via a sh...
