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...

The randomized clinical trial (RCT) is a powerful experimental design that when properly executed produces generalizable results. Conducting a RCT becomes complex when technical skills are required. Without requisite skills, a RCT may yield misleading results, an elegant RCT unwittingly generating spurious results due to technical inexperience. This pitfall is applicable to procedures used to e...
