Design of CMOS CFOA Based on Pseudo Operational Transconductance Amplifier

A novel design technique employing CMOS Current Feedback Operational Amplifier (CFOA) is presented. The feature of consumption very low power in designing pseudo-OTA is used to decreasing the total power consumption of the proposed CFOA. This design approach applies pseudo-OTA as input stage cascaded with buffer stage. Moreover, the DC input offset voltage and harmonic distortion (HD) of the pr...

Design of Two Stage Ultra Low Power CMOS Operational Transconductance Amplifier (OTA) Using 180 nm Technology

This paper deals with well-defined design criteria for ultra low power two stage CMOS operational transconductance amplifiers (OTAs) with simple yet robust implementation in nm dimension. A simple design approach which allows electrical parameters to be univocally related to each circuit element and biasing values for low frequency applications is presented.The operational transconductance ampl...

24GHz CMOS direct downconversion receiver front-end and VCO design

The explosive growth of today's wireless communication market has brought an in­ creasing demand for high performance radio-frequency (RF) circuits in low-cost tech­ nologies. Because of advancements in RF CMOS circuits, devices, and passive elements in the last decade, it has become possible to develop a RF system-on-chip (SoC) that integrates RF, analog and digital circuits completely. Direct...

Assessment and Design Enhancement of the Front End Energy Absorption Mechanism of a Locomotive Based on an Impact Scenario

This research is concerned with weighing the behavior of the front end energy absorption system of a locally manufactured locomotive in crash situations. The causes of the extensive damages to the energy absorption apparatus that includes the crash element and the buffer are studied. By choosing the proper damage model the conditions of the accident is simulated by using the ABAQUS engineering ...
