Here the outputs of the comparators are encoded using Exclusive-OR gates before being fed to the diodes. Two external pull-down resistor are used at their outputs and ground (0V) to ensure a LOW condition and stop the outputs from floating when the diodes are reverse biased.

Webuse a single-ended connection scheme to the ADC. It makes no sense to purchase a fully differential op amp, and then not use the differential output to interface to the differential input of the ADC. In most cases, the dual supply implementation is a trivial change from the single-supply implementation, so schematics may not be included. Flash ADCs have been implemented in many technologies, varying from silicon-based bipolar (BJT) and complementary metal–oxide FETs (CMOS) technologies to rarely used III-V technologies. Often this type of ADC is used as a first medium-sized analog circuit verification. The earliest implementations consisted of a reference ladder of well matched …
WebJan 9, 2024 · In a BJT (Bipolar Junction Transistor), say NPN in common base configuration, we forward bias the Base-Emitter Junction and reverse bias the Base-Collector Junction when using a constant DC supply. Intuitively, when I replace DC with AC, the polarity changes after every half cycle. And this means, the Base-Emitter Junction is … WebA converter that is used to change the analog signal to digital is known as an analog to digital converter or ADC converter. This converter is one kind of integrated circuit or IC that converts the signal directly from continuous form to discrete form. This converter can be expressed in A/D, ADC, A to D.
