This paper describes a feedthrough reduction technique for a track-and-hold (T/H) circuit with a body-bias control circuit. We propose a T/H circuit with a feedthrough canceller. This circuit cancels a leaking signal to the output node through the parasitic capacitance by using an opposite-phase signal. The simulation results using 90-nm CMOS technology demonstrate a feedthrough of −89.4 dB and...

A 4 order RF LC Σ∆ ADC clocked at 3.6GHz and centered at 900MHz is presented. The simplicity of the ADC architecture results in a significant performance enhancement and power consumption reduction. The ADC, suitable for Software Defined Radio applications, is implemented in a standard 130nm CMOS technology. It achieves a 52dB SFDR and a 50dB SNDR in a 28MHz BW and consumes only 15mW from a 1.2...

KEY FINDINGS Data from the National Ambulatory Medical Care Survey, 2012 •Physician office visit rates for well care were lower for school-aged (those aged 6-11 years) children (31 per 100 population) and adolescents aged 12-17 years (29 per 100 population) than for younger children (349 and 74 per 100 population for children under age 1 year and 1-5 years, respectively). •Visit rates for well ...

The second step is information. It should be clear, simple and repetitive, keeping in mind that we only hear what interests us. Therefore, it is important to repeat and repeat, with different approaches, again and again. A well informed patient is better equipped to assume the treatment. The information is completely our responsibility; it should be verbal, written and visual1-3. It should be n...
