This paper on "Smart Irrigation System" is develop to create an automated irrigation mechanism which turns the pumping motor ON and OFF on detecting the moisture content of the earth using the soil moisture sensor without the intervention... more
Operational Amplifier (Op Amp) is a three terminal electronic device which has two inputs of high impedance. The first input is called inverting (represented by ‘-‘), and the other terminal is called non-inverting input. The third... more
The design of a linear integrated Op Amp circuit as an alternative solution to differential equation model of RLC Circuit is presented. The fundamental assumption used in the cascaded Operational Amplifier (Op Amp) design is that Op Amp... more
Penguat Instrumasi Menggunakan Op Amp, Penguat Transkonduktansi, Penguat Logaritmik, Rangkaian Sumber Arus Konstan Menggunakan Penguat Operasional, Rangkaian Pengubah Arus Ke Tegangan, Rangkaian Detektor Puncak, dan Rangkaian Control... more
This paper describes about different types of voltage followers. Each follower has its own advantages and limitations. The voltage follower can be characterized with current mirror source current or it can be used as a ideal current... more
Practice #1 of Operational Amplifiers
Here are some tasks about operational amplifiers, to see how your students understand.
In design of analog circuits not only the gain and speed are important but power dissipation, supply voltage, linearity, noise and maximum voltage swing are also important. Noise limits the minimum signal level that a circuit can process... more
VLC is a complex system with lots of challenges in its implementation. One of its problems is noise that originated from internal and external sources (sunlight, artificial light, etc). Internal noise is originated from active components... more
— While the selection of new "backbone" device structure in the era of post-planar CMOS is open to a few candidates, FinFET and its variants show great potential in scalability and manufacturability for nanoscale CMOS. In future, as the... more
In this paper dynamic biasing technique is used for the enhancing the slew rate of the designed Op-Amp. The proposed FinFET based Op-Amp has been verified through Hspice simulator in the standard 45nm Silicon on Insulator FinFET library.... more
Bond graph is an integrated method of modeling which would be suitable for modeling mechatronic systems that are usually formed from electrical, mechanical and hydraulic systems. This paper presents a new bond graph model for one the... more
Inverter is an obvious device to utilize the renewable energy resources. Pulse width modulation (PWM) technique is the most used technique for inverters. This paper represents the Sinusoidal PWM technique and shows how to generate PWM... more
This paper presents the design of a first order and second order single bit Sigma-Delta Analog-to-Digital Converter (ADC) which is realized using CMOS technology. In this paper, a first Order and Second order Sigma-Delta ADC is designed... more
I. INTRODUCTION The minimum supply voltage in low-voltage circuits can be defined as Vsup,min = 2(Vgs + V,,,) [I]. Low-voltage cir- cuits are able to operate on a supply voltage of two stacked gate-source voltages and two ...
