A High-accuracy, Zero-crossing-based Pipeline ADC
نویسندگان
چکیده
Technology scaling poses challenges in designing analog circuits because of the decrease in intrinsic gain and reduced swing. An alternative to using highgain amplifiers in the implementation of switched capacitor circuits has been proposed [1] that replaces the amplifier with a current source and a comparator. The new comparator-based switch capacitor (CBSC) and zero-crossing-based circuit (ZCBC) techniques have been implemented in two pipelined ADC architectures at 10MHz and 200MHz and 10-bit and 8-bit accuracy, respectively [1], [2].

A High Performance Zero - Crossing Based Pipelined Analog - to - Digital Converter
In this thesis, I describe a zero-crossing based pipelined ADC. Unlike traditional pipelined ADCs, this work does not use any op-amps in the signal path. The use of zero-crossing based circuits made it possible to achieve a much better figure of merit. The ADC is design to operate at 200MS/s with a resolution of 12 bits. The simulated results suggest that the target performance is achievable wi...
متن کاملTechniques for Low - Power High - Performance ADCs
Analog-to-digital converters (ADCs) are essential building blocks in many electronic systems which require digital signal processing and storage of analog signals. Traditionally, ADCs are considered a power hungry circuit. This thesis investigates ADC design techniques to achieve high-performance with low power consumption. Two designs are demonst rated. The first design is a voltage scalable z...

Comparator-based switched-capacitor (CBSC) circuits were introduced in [1] as an alternative to opamp-based designs to overcome the limitations of opamps due to device and voltage scaling. Reduced device gain and signal swing make it increasingly difficult to design high-gain high-speed feedback loops with opamps. CBSC circuits replace the opamp with a comparator and a current source (see U1 an...

متن کاملStatic Characterization of Arbitrary Waveform Generator based on Modified Multi- sine Fitting and Zero Crossing Detection Algorithms
The static characterization of the output section of the Arbitrary Waveform Generator (AWG) requires that its output signal must be digitalized by Analog to Digital Converter (ADC) with higher linearity and resolution than the device under test. In the literature, the problem of high resolution acquisition is translated to the simpler problem of low resolution and high sampling frequency acquis...
