This paper presents a calibration-less inverter-based operational transconductance
amplifier (OTA) built with intrinsically matched CMOS inverters, therefore, dispensing any …

This work presents an Operation Transconductance Amplifier with improved common mode
rejection based in both Nauta's and Vieru's push–pull based OTAs operating at a 0.5 V …

This manuscript presents a fully differential difference transconductance amplifier (FDDTA)
architecture based on CMOS inverters. Designed in a 130-nm CMOS process it operates in …

This paper investigates the effect of Electromagnetic Interferences (EMI) on inverter-based
analog amplifiers, as the Nauta operational transconductance amplifier (OTA). We show …

The power dissipated by the active-RC filters is mainly due to the operational amplifier
power dissipation since it is the only active block employed. On the other hand, the power …

This thesis proposes novel circuit topologies and design techniques of ultra-low voltage
(ULV) and ultra-low power (ULP) active-filters and programmable gain amplifiers (PGA) …

From the birth of the first digital computers, Analog-to-Digital Converters (ADCs) have
gained more and more importance in every fields of electronics. From very high-speed …

In this chapter, the design of the circuits presented in this book is analyzed, and a design
tool based on the operation-point is introduced as an alternative to the transistor sizing of the …

Nos processos de fabricação de amplificadores diferenciais integrados uma característica
inerente é que os transistores nMOS e pMOS construídos possuam diferenças físicas em …

Este trabalho propõe novas topologias de circuitos e técnicas de projeto para filtros ativos e
amplificadores de ganho programável (PGA) com operação em ultra baixa tensão (ULV) e …
