Simulation results with CMOS 0.18μm technology show that the gain can be programmed from-14dB to -32dB with 2dB step, step accuracy and absolute accuracy are ±0.15 and ±0.25.

The device structure being considered has a wide separation between source-gate and drain-gate with a shallow trench isolation (STI) technique. High noise level is found in the devices with STI and the normalized drain noise is found to be gate bias dependent. The excess noise is identified as the surface noise generated in the STI regions and a model is developed to explain the bias dependence of the noise characteristics. To reduce the noise level, the STI region should be kept small and better oxidation technique should be employed for the STI passivation.","PeriodicalId":429314,"journal":{"name":"2005 IEEE Conference on Electron Devices and Solid-State Circuits","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129802585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When testing with different loads [1], the output obtained has good voltage regulator, a wide input voltage range, quick response and safe. This research uses phototransistor to detect output current signal and send feedback with isolated electrical signal to PWM (Pulse Width Modulation) circuit to control the duty cycle fed to switch. Buck converter is a step down voltage converter, which results in the current at output higher than that of input [2]. This research uses output current fed through Opto and select only linear interval current ratio fed to control and feedback. The experiment is performed using Buck-Type DC-DC converter to level the output voltage as desired.Results are satisfying and a simplest circuit.","PeriodicalId":429314,"journal":{"name":"2005 IEEE Conference on Electron Devices and Solid-State Circuits","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114819043","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
