| 1 | Digitally controlled oscillator design with a variable capacitance XOR gate显示文摘A digitally controlled oscillator(DCO) using a three-transistor XOR gate as the variable load has been presented.A delay cell using an inverter and a three-transistor XOR gate as the variable capacitance is also proposed. Three-,five- and seven-stage DCO circuits have been designed using the proposed delay cell.The output frequency is controlled digitally with bits applied to the delay cells.The three-bit DCO shows output frequency and power consumption variation in the range of 3.2486-4.0267 GHz and 0.6121-0.3901 mW,respectively,with a change in the control word 111-000.The five-bit DCO achieves frequency and power of 1.8553-2.3506 GHz and 1.0202-0.6501 mW,respectively,with a change in the control word 11111-00000.Moreover,the seven-bit DCO shows a frequency and power consumption variation of 1.3239-1.6817 GHz and 1.4282-0.9102 mW,respectively, with a varying control word 1111111-0000000.The power consumption and output frequency of the proposed circuits have been compared with earlier reported circuits and the present approaches show significant improvements. | Manoj Kumar Sandeep K.Arya Sujata Pandey | 2011 | Journal of Semiconductors2011，32，10： | 2 |
| 2 | Low power digitally controlled oscillator designs with a novel 3-transistor XNOR gate显示文摘Digital controlled oscillators(DCOs) are the core of all digital phase locked loop(ADPLL) circuits. Here,DCO structures with reduced hardware and power consumption having full digital control have been proposed. Three different DCO architectures have been proposed based on ring based topology.Three,four and five bit controlled DCO with NMOS,PMOS and NMOS & PMOS transistor switching networks are presented.A three-transistor XNOR gate has been used as the inverter which is used as the delay cell.Delay has been controlled digitally with a switch network of NMOS and PMOS transistors.The three bit DCO with one NMOS network shows frequency variations of 1.6141-1.8790 GHz with power consumption variations 251.9224-276.8591μW. The four bit DCO with one NMOS network shows frequency variation of 1.6229-1.8868 GHz with varying power consumption of 251.9225-278.0740μW.A six bit DCO with one NMOS switching network gave an output frequency of 1.7237-1.8962 GHz with power consumption of 251.928-278.998μW.Output frequency and power consumption results for 4 & 6 bit DCO circuits with one PMOS and NMOS & PMOS switching network have also been presented.The phase noise parameter with an offset frequency of 1 MHz has also been reported for the proposed circuits.Comparisons with earlier reported circuits have been made and the present approach shows advantages over previous circuits. | Manoj Kumar Sandeep K.Arya Sujata Pandey | 2012 | Journal of Semiconductors2012，33，3： | 0 |

| 4 | Risk factors for development of pneumothorax in patients with COVID-19 at a government health facility in North India:An exploratory case-control study显示文摘Objective:To explore risk factors for the development of pneumothorax in patients with COVID-19 during the second COVID-19 wave at a northern Indian level 2 health facility.Methods:Patients suffering from SARS-CoV-2 infection during the second wave of the COVID-19 pandemic in India(January-June 2021)at a tertiary care teaching hospital and level 2 COVID care facility were included.Cases who suffered from SARS-CoV-2 infection but did not develop pneumothorax were selected as matched controls.All details regarding demographics,clinical presentation,treatment,and outcome were recorded in a semi-structured proforma.Results:Eleven patients with COVID-19 developed pneumothorax during the study period and 40 controls were included in the study.Five cases were smokers in comparison to only two in the control group.Type 2 diabetes mellitus was the most common comorbidity among both groups.Median change in C-reactive protein overall for cases and controls were around+14.0 and-41.9 and was statistically significant.Conclusions:Inflammatory markers like C-reactive protein have significant correlations with the development of pneumothorax in COVID-19-infected patients.There is no sex predisposition to develop pneumothorax among patients with COVID-19. | Manabendra Baidya Sandeep Kumar Pandey Hariom Kumar Solanki Ankur Deep Singh Samaksh Giri Syed Altamash | 2023 | Journal of Acute Disease2023，12，6： | 0 |
