A High Swing Ultra-Low-Power Two Stage CMOS OP-AMP in 180 nm and 350nm Technology with 1.5V supply, is presented. Cascode technique has been used to increase the dc gain. The unity-gain bandwidth is also enhanced using a gain-stage in the Miller capacitor feedback path. It have 92.45 degree phase margin. The circuit has 94.866dB gain for 180nm. The power dissipation of the designed only is appr...

––Data de-duplication is a very simple concept with very smart technology associated in it. The data blocks are stored only once, de-duplication systems decrease storage consumption by identifying distinct chunks of data with identical content. They then store a single copy of the chunk along with metadata about how to reconstruct the original files from the chunks, this takes up the less stora...

A novel topology for a high gain two-stage amplifier is proposed. The proposed circuit is designed in a way that the non-dominant pole is at output of the first stage. A positive capacitive feedback (PCF) around the second stage introduces a left half plane (LHP) zero which cancels the phase shift introduced by the non-dominant pole, considerably. The dominant pole is at the output node which m...

BACKGROUND Recently, several adaptive one-arm two-stage designs have been developed by fully using the information from previous stages to reduce the expected sample size in clinical trials with binary endpoints as primary outcome. It is important to compute exact confidence limits for these studies. METHODS In this article, we propose three new one-sided limits by ordering the sample space b...

Due to the low voltage of PV module and enable AC technology, where every has its own DC-AC converter, this paper introduces a new high step-up seven-level two-stage multilevel inverter for grid-connected Photovoltaic (PV) system. The introduced schematic consists two stages. first stage is switched capacitor boost converter second seven-switches inverter. designed extract maximum power input v...

A two stage position-sensitive gas proportional counter has been constructed by tightly coupling a Gas Electron Multiplier (GEM) with a Micro-Groove Detector (MGD). The GEM was used as the first amplifying stage and was optimised to transmit close to 100 % of the primary charge even at very high drift fields (10 kV/cm). Very narrow GEM– MGD separations (0–600 m) were used so that the active vol...

This paper presents a two-stage low-noise ultra-wideband amplifier to obtain high and smooth gain in 180nm CMOS Technology. The proposed structure has two common source stages with inductive feedback. First stage is designed about 3GHz frequency and second stage is designed about 8GHz. In simulation, symmetric inductors of TSMC 0.18um CMOS technology in ADS software is used.Simulations results ...
