All-optical analog comparator
An analog comparator is one of the core units in all-optical analog-to-digital conversion (AO-ADC) systems, which digitizes different amplitude levels into two levels of logical '1' or '0' by comparing with a defined decision threshold. Although various outstanding photonic ADC approaches have been reported, almost all of them necessitate an electrical comparator to carry out this binarization....
متن کاملComparator-based switched-capacitor pipelined analog-to-digital converter with comparator preset, and comparator delay compensation
We present a differential comparator-based switched-capacitor (CBSC) pipelined analog-to-digital converter (ADC) with comparator preset, and comparator delay compensation. Compensating for the comparator delay by digitally adjusting the comparator threshold improves the ADC resolution from 2.5-bit to 7.05-bit. The ADC is manufactured in a 90 nm CMOS technology, with a core area of 0.85 mm 9 0.3...

متن کامل1-V CMOS Comparator for Programmable Analog Rank-Order Extractor
A CMOS rail-to-rail comparator operating at low-voltage supply by using a conventional fabrication process is proposed. Based on the comparator, an analog rank-order extractor with winner-take-all capability is presented. An experimental chip was fabricated using 0.5 m CMOS technology. Measured results at 1–V supply voltage show a comparator response time of 4 s for 10-mV precision and that the...
متن کاملA New Design of Fault Tolerant Comparator
In this paper we have presented a new design of fault tolerant comparator with a fault free hot spare. The aim of this design is to achieve a low overhead of time and area in fault tolerant comparators. We have used hot standby technique to normal operation of the system without interrupting and dynamic recovery method in fault detection and correction. The circuit is divided to smaller modules...
