TL;DR: In this paper, the authors present the evaluation and performance analysis of 5 stage Current Starved Voltage Controlled ring Oscillator (CSVCO) which employs the method of linearization technique.
Abstract: This paper presents the evaluation and performance analysis of 5 stage Current Starved Voltage Controlled ring Oscillator (CSVCO) which employ the method of linearization technique. In this technique, a source degeneration method has been utilized which makes the output frequency of oscillation more linear with respect to control voltage. The simulation of the circuit is accomplished by using 180nm CMOS technology. The proposed CSVCO has achieved frequency range from 108MHz to 2.14GHz and power consumption of 121.54µW with the constant supply voltage of 1.8V and phase noise is -90 dbc/Hz.

TL;DR: How traditional agriculture in India can be replaced with smart and precision agriculture by controlling different parameter using programmed hardware through Verilog hardware description language with available sensor network data to develop an ASIC is explained.
Abstract: Objective of this paper to explain how traditional agriculture in India can be replaced with smart and precision agriculture by controlling different parameter using programmed hardware through Verilog hardware description language with available sensor network data to develop an ASIC. There are different parameters which are responsible for growth of plant, by controlling that parameter production and growth of plant can be improved rapidly in compare of traditional agriculture Issue in traditional agriculture can easily remove through precision agriculture based network. Using precision agriculture organic farming can possible so disease cause by inorganic farming can overcome easily. Water supply in traditional agriculture is more than need of plant so more energy consume to supply more water, using precision agriculture water supply according to need of plant so energy conservation possible. Data analysis of agriculture sector can give correct information about consumption and production of different crops, vegetables, fruits. According to data analysis farmer can easily grow different crops according to demand with the help of precision agriculture.

TL;DR: In this paper, a 6-bit LC tuned digitally controlled oscillator (DCO) based on low-power and low-phase noise was proposed, which achieved 6.33 mW power consumption at 1.8 V supply voltage and also achieved low phase noise that is −126.28 dBc/Hz at 1 MHz offset frequency.
Abstract: This paper proposes a 6-bit LC tuned digitally Controlled Oscillator (DCO) based on low-power and low-phase-noise. In this proposed design NMOS varactor weighing were implemented. The proposed DCO with capacitive degeneration oscillates at a frequency that can be tuned from 2.28-to-2.74 GHz with 20% tuning range. In proposed circuit we have achieved 6.33 mW power consumption at 1.8 V supply voltage and also achieved low phase noise that is −126.28 dBc/Hz at 1 MHz offset frequency.

TL;DR: Aujourd’hui toute l’électronique se concentre sur une puce, and les logiciels de simulation utilisés sont plutôt du type VHDL, voire mixte continu/événementiel, mais dont the plupart sont inspirés de SPICE.
Abstract: SPICE est un logiciel qui m’a beaucoup émerveillé lorsque j’étais étudiant, de par sa puissance et sa simplicité d’utilisation. Il est vrai que nous faisions beaucoup de travaux pratiques en électronique, et le simple fait de pouvoir mettre son circuit sous forme de liste, appelée netlist, et de le simuler était une découverte fascinante. SPICE a servi de modèle à nombre d’autres programmes de simulation, dans les universités et dans l’industrie, grâce à son modèle précoce Open Source. Aujourd’hui toute l’électronique se concentre sur une puce, et les logiciels de simulation utilisés sont plutôt du type VHDL [1], voire mixte continu/événementiel [2], mais dont la plupart sont inspirés de SPICE. Actuellement, on édite de manière graphique son schéma et on lance directement la simulation depuis son interface graphique. Ce qu’il faut savoir c’est que bon nombre de ces interfaces graphiques construisent une netlist et c’est un SPICE adapté qui fera la simulation par-derrière. La première version de SPICE date de 1972 et a été écrite en fortran, rapidement suivie par la deuxième version en 1975. Il faudra attendre 1989 pour voir la troisième version (définitive) de SPICE, écrite en C. Il est remarquable d’observer que la troisième version fût la dernière, avec des mises à jour mineures et qui se déclinent en lettre, la dernière étant 3f5. Aujourd’hui, et dans cet article, on utilisera Ngspice [3] qui est basé sur la dernière version de SPICE, et qui se trouve sous licence GNU GPL2. Il est fourni par le groupe de développement gEDA [4] qui a repris le flambeau pour le développement de tous les logiciels de simulation ou de conception de circuits électroniques.

TL;DR: In this paper, the surface potential-based compact transistor model, MOS Model 20 (MM20), has been extended with a quasi-saturation, an effect that is typical for LDMOS devices with a long drift region.
Abstract: The surface-potential-based compact transistor model, MOS Model 20 (MM20), has been extended with a quasi-saturation, an effect that is typical for LDMOS devices with a long drift region As a result, MM20 extends its application range from low-voltage LDMOS devices up to high-voltage LDMOS devices of about 100V In this paper, the new dc model of MM20, including quasi-saturation, is presented The addition of velocity saturation in the drift region ensures the current to be controlled by either the channel region or the drift region A comparison with dc measurements on a 60-V LDMOS device shows that the new model provides an accurate description in all regimes of operation, ranging from subthreshold to superthreshold, in both the linear and saturation regime Thus, owing to the inclusion of quasi-saturation also the regime of high-gate and high-drain bias conditions for high-voltage LDMOS devices is accurately described

TL;DR: A set of characterization vehicles that can be employed to quantify the analog behavior of active and passive devices in CMOS processes, in particular, properties that are not modeled accurately by SPICE parameters are described.
Abstract: The design of analog and radio-frequency (RF) circuits in CMOS technology becomes increasingly more difficult as device modeling faces new challenges in deep submicrometer processes and emerging circuit applications. The sophisticated set of characteristics used to represent today's ?>digital ?> technologies often proves inadequate for analog and RF design, mandating many additional measurements and iterations to arrive at an acceptable solution. This paper describes a set of characterization vehicles that can be employed to quantify the analog behavior of active and passive devices in CMOS processes, in particular, properties that are not modeled accurately by SPICE parameters. Test structures and circuits are introduced for measuring speed, noise, linearity, loss, matching, and dc characteristics.
