The LT®6600-20 combines a fully differential amplifi er with a 4th order 20MHz lowpass fi lter approximating a Chebyshev frequency response. Most differential amplifi ers require many precision external components to tailor gain and bandwidth. In contrast, with the LT6600-20, two external resistors program differential gain, and the fi lter’s 20MHz cutoff frequency and passband ripple are inter...

This paper explores the potential advantage of surrounded gate junctionless graded channel (SJLGC) MOSFET in view its Analog, RF performances using ATLAS TCAD device simulator. The impact lateral direction on potential, electric field, and velocity carriers, energy band along is investigated systematically. present work mainly emphasises superior performance SJLGC by showing higher drain curren...

We reconsider stochastic resonance (SR) for an overdamped bistable dynamics driven by a harmonic force and Gaussian noise from the viewpoint of the gain behavior, i.e., the signal-to-noise ratio (SNR) at the output divided by that at the input. The primary issue addressed in this work is whether a gain exceeding unity can occur for this archetypal SR model, for subthreshold signals that are bey...

A fast settling multipath CMOS OTA for high speed switched capacitor applications is presented here. With the basic topology similar to folded-cascode, bandwidth and DC gain of the OTA are enhanced by adding extra paths for signal from input to output. Designed circuit is simulated with HSPICE using level 49 parameters (BSIM 3v3) in 0.35 um standard CMOS technology. The DC gain achieved is 56.7...

Designers of quality audio equipment have long recognized the value of a low noise gain block with “audiophile performance”. The LM833 is such a device: a dual operational amplifier with excellent audio specifications. The LM833 features low input noise voltage typical), large gain-bandwidth product (15 MHz), high slew rate (7V/μSec), low THD (0.002% 20 Hz-20 kHz), and unity gain stability. Thi...

We report the measurement of intermodulation gain greater than unity in NbN superconducting stripline resonators. In the intermodulation measurements we inject two unequal tones into the oscillator—the pump and signal—both lying within the resonance band. At the onset of instability of the reflected pump we obtain a simultaneous gain of both the idler and the reflected signal. The measured gain...

In this paper, we report record radio frequency (RF) performance of carbon nanotube transistors based on combined use of a self-aligned T-shape gate structure, and well-aligned, high-semiconducting-purity, high-density polyfluorene-sorted semiconducting carbon nanotubes, which were deposited using dose-controlled, floating evaporative self-assembly method. These transistors show outstanding dir...
