The design of an N -comparator based asynchronous Successive Approximation Analog-to-Digital Converter (SAR ADC) is described (with N = 6) working at 20 MS/s and consuming only 5.6 mW for low power high speed applications like communication systems. Resetting the comparators in each conversion cycle is avoided (reducing power consumption compared to [1]) and only N latches are used overall (inc...

We have designed, fabricated and tested the second-generation (2G) design of a high-resolution, dynamically programmable analog-to-digital converter (ADC) for radar and communications applications. The ADC chip uses the phase modulation–demodulation architecture and on-chip digital filtering. The 2G ADC design has been substantially enhanced. Both ADC front-end modulator and demodulator, as wel...

The Transition Radiation Detector (TRD) of the ALICE experiment at CERN incorporates 1.2 million channels which are individually read out and processed. The front-end electronics (FEE) utilizes two custom chips: an 18 channel analog preamplifier and shaper (PASA) and a mixed-signal chip, performing 10 bit analog-to-digital conversion, event buffering and local tracking (TRAP). Both chips togeth...

This paper presents a 14-bit cyclic-pipelined Analog to digital converter (ADC) running at 1 MS/s. The architecture is based on a 1.5-bit per stage structure utilizing digital correction for each stage. The ADC consists of two 1.5-bit stages, one shift register delay line, and digital error correction logic. Inside each 1.5-bit stage, there is one gain-boosting op-amp and two comparators. The A...

In this paper, a differential cyclic analog-to-digital converter based in switched-capacitor techniques is presented. This approach allows a reduced die size and achieves a higher precision, making this circuit suitable to low speed measurements, such electric energy meter systems where a minimum sampling rate of 1,200 samples per second is required for 2-channel systems (single-phase) and 7,60...

The digital processing signal is one of the subdivisions of the analog digital converter interface; data transfer rate in modern telecommunications is a critical parameter. The greatest feature of parallel conversion rate (4-bit parallel Flash 5/s converter) is designed and modeled in 0.18 micron CMOS technology. Low speed swing operation as analog and digital circuits leads to high speed of lo...

This paper presents a single-bit CMOS image sensor (CIS) that uses a data processing technique with an edge detection block for simple iris segmentation. In order to recognize the iris image, the image sensor conventionally captures high-resolution image data in digital code, extracts the iris data, and then compares it with a reference image through a recognition algorithm. However, in this ca...
