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 کاملDesigning an Integrated All-Optical Analog to Digital Converter
We present the procedure for designing a high speed and low power all-optical analog to digital converter (AO-ADC), by integrating InGaAsP semiconductor optical amplifier (SOA) with InP based photonic crystal (PhC) drop filters. The self-phase modulation in the SOA can shift the frequency of the Gaussian input pulse. The two output PhC based drop filters are designed to appropriately code the f...
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 کاملChip-integrated ultrawide-band all-optical logic comparator in plasmonic circuits
Optical computing opens up the possibility for the realization of ultrahigh-speed and ultrawide-band information processing. Integrated all-optical logic comparator is one of the indispensable core components of optical computing systems. Unfortunately, up to now, no any nanoscale all-optical logic comparator suitable for on-chip integration applications has been realized experimentally. Here, ...
