This paper analyzes a pseudo-differential dynamic comparator with a dynamic pre-amplifier. The transient gain of a dynamic preamplifier is derived and applied to equations of the thermal noise and the regeneration time of a comparator. This analysis enhances understanding of the roles of transistor’s parameters in pre-amplifier’s gain. Based on the calculated gain, two calibration methods are a...

We survey recent results on periodic algorithms. We focus on the problems of sorting, merging and permuting and concentrate on algorithms that have small constant periods.

A novel circuit based on sign detection is introduced in this paper which uses the subtraction for comparing two numbers without carrying out a full comparison and conversion. Thus, the proposed schema decreases the delay significantly using only a little redundant hardware in contrast to previous works. Also the time complexity of the new design has the best results comparing to the previous w...

A 0.6-V voltage shifter and a 0.6-V clocked comparator are presented for sampling correlation-based impulse radio UWB receiver. The voltage shifter is used for a novel split swing level schemebased CMOS transmission gate which can reduce the power consumption by four times. Compared to the conventional voltage shifter, the proposed voltage shifter can reduce the required capacitance area by hal...

Abstract — A new dynamic comparator is proposed and it is compared with two existing comparators in terms of voltage, delay and frequency. CMOS dynamic comparator which has dual input, dual output inverter stage suitable for high speed ADCs with low voltage and low power dissipation. A conventional comparator is replaced with dynamic comparator which reduces the delay and voltage which increase...

OBJECTIVE To compare the effects on back pain of teriparatide versus alendronate, we analyzed the reporting of back pain in a head to head comparator trial and a followup study. METHODS In the comparator trial, women were randomized to receive either daily self-injected teriparatide 40 microg plus an oral placebo (n = 73), or daily oral alendronate 10 mg plus self-injected placebo (n = 73). T...

OBJECTIVE The objective of this study was to determine whether the effectiveness of budesonide comparator is non-inferior to budesonide reference in the prevention of asthma exacerbations. Asthma-related hospitalizations and safety were also examined. METHODS This study used a matched, historic cohort design. Data were drawn from the Clinformatics™ Data Mart US claims database and included a ...
