A flux-controlled memristor using complementary metal–oxide–(CMOS) structure is presented in this study. The proposed circuit provides higher power efficiency, less static dissipation, lesser area, and can also reduce the supply by CMOS 90nm technology. implemented based on use of a second-generation current conveyor (CCII) operational transconductance amplifier (OTA) with few passive elements....

Technology development and continuous down scaling in CMOS fabrication makes Mixed Signal Integrated Circuits (MSIC) more vulnerable to process variation. This paper presents a well defined novel design methodology for process variability aware design by incorporating the major challenge of statistical circuit performance relating the device and circuit level variation in an accurate and effici...

Read/write channels for hard disk drives (HDD) require high-frequency continuous time filters (CTF) [1-5]. A 650 MHz current-mode seventh-order 0.05° equiripple linear phase low-pass filter for computer hard disk read/write channels with data rates up to 1Gbit/s is presented in this paper. It is implemented in CMOS using a leap-frog multiple loop feedback structure. The operational transconduct...

Operational amplifiers are important building blocks for analog circuit design. Unfortunately, their limited performance such as bandwidth, slew-rate etc. leads the analog designer to search other possibilites and other building blocks. As a result, new current-mode active building blocks such as operational transconductance amplifiers (OTA), second generation current conveyors (CCII), current-...

We present a low voltage, low power operational transconductance amplifier (OTA) designed using a Fully Depleted Silicon-on-Insulator (FDSOI) process. For very low voltage application down to 0.5 V, two-stage miller-compensated OTAs with both p-channel MOSFET (PMOS) and n-channel MOSFET (NMOS) differential input have been investigated in a FDSOI complementary metal oxide semiconductor (CMOS) 15...

High Performance Continuous-time Filters for InformationTransfer Systems. (August 2003)Ahmed Nader Mohieldin, B.Sc., Cairo University, Egypt;M.Sc., Cairo University, Egypt;Chair of Advisory Committee: Dr. Edgar Sánchez-Sinencio Vast attention has been paid to active continuous-time filters over the years. Thus asthe cheap, readily available integrated circuit OpAmps replaced...

This paper presents the design of an ultra low-voltage (ULV) pseudo operational transconductance amplifier (P-OTA) that is able to operate with a single supply voltage as low as 0.4 V. The proposed circuit is based on the bulk-driven technique and use of cross-coupled self-cascode pairs that boosts the differential DC gain. The stability condition of this structure for the DC gain is considered...

A third-order Chebyshevlow-pass filter, using Gm-C structure, based on Nauta’s OTA, is presented. The filter is designed for 60GHz wireless communication using 65nm CMOS process and 1.2V power supply. The cutoff frequency of the filter is required to be tuned from 1GHz to 5GHz.UsingNauta’stransconductance characteristics, the filter can be operated at ultra-high frequency band and has a high li...
