Counter type ADC
One of the simplest types of the ADC is the Counter type ADC. The input signal of the ADC is connected to the signal input of its internal comparator. ADC then systematically increases the voltage on the reference input of the comparator until the reference becomes larger than the signal & the comparator output goes to zero.

flash type ADC is fastest because in it change takes place simultaneously not sequentially time taken for conversion is 100 ns.
a type of ring counter
they are same expect error .in adc0809 1/2 lsb unadjusted error is present and in adc 0809 1lsb error is present.
If you are using XILINX FPGA, try to insert a Microblaze processor to control your ADC.
You will have to determine its scaling factor. The output of the ADC is a number, you can interpret it anyway that is necessary for the system it is in.
Types Of ADC Are As follows: 1.Counter type ADC 2.Successive approximation type ADC 3.Flash Type ADC 4.Wilkinson type ADC
The main disadvantage of dual slope adc or integrated type adc is its long conversion time
answer is 1. sigma delta ADC which is used to improve resolution of the ADC by oversampling
flash type ADC is fastest because in it change takes place simultaneously not sequentially time taken for conversion is 100 ns.
Basic adc
Usually with an ADC of some type, but this can vary with the type of sensor. Most modern microcontrollers contain at least one built in ADC usually with a multiplexer allowing measurement of multiple sensors.
The voltage at which the adc converts the signal.... it can also be called a limit of an ADC.
