چکیده

We describe an optically assisted folding-flash analog-to-digital converter. The periodic transfer function of the Mach-Zehnder interferometer is used to perform analog folding on the electronic signal to be quantized. A novel analog encoding scheme for efficient generation of gray code digital data is proposed. The new encoding scheme eliminates the requirement for interferometers with ultralow V(pi), which, so far, has hindered the development of such systems. The encoding concept is experimentally demonstrated through the use of LiNbO(3) modulators.

Designing 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...

An 8-b 650-MHz Folding ADC

An 8-b 650-MHz folding analog-to-digital converter (ADC) with analog error correction in the comparators is presented. With an input frequency of 150 MHz, 7.8 effective bits are obtained. The ADC is implemented in a 1-pm 13-GHz triple-level interconnect bipolar process, requiring 850 mW from a single -4.5-V supply. The die size is 4.2 mm’.

Design of a Cmos 6-bit Folding and Interpolating Analog to Digital Converter

This thesis describes the design of a 6-bit CMOS folding and interpolating Analog to Digital Converter (ADe). Folding and interpolating techniques can be used in CMOS flash type ADCs so that less die area and power dissipation are used. while at the same time maintaining high-speed operation. The fundamentals of the CMOS folding and interpolating circuits are covered, and some of the major desi...
