Abstract |
|
This paper presents the design and analysis of Telescopic OTA. Here, Telescopic OTA is designed for 350nm Technology with ±2V power supply voltage using Tanner tool. The simulation results of this OTA shows differential gain, Phase Margin, UGB, CMRR, PSRR, power dissipation, which are the basic performance parameters of an OTA. Various process parameters like Threshold Voltage, Temperature, Oxide thickness, Supply voltage shows remarkable changes on performance parameters. The effect of threshold voltage, temperature and supply voltage on differential gain is shown. Many researches showed the inherent disadvantage of low output swing of Telescopic OTA. The effect of process parameters is also checked on Offset Voltage Swing. |
