thermometer coded

What code? Serial code? Data code? Batch code? Health department code? Product code?

digital thermometer code

i need to design analog circuit for flash ADC. There i came across a circuit in which the comparator output is to be coded.

what is thermometer code

Hi,

The digital thermal code for a flash ADC assembles that of a thermometer (obvious eh? =)). Unlike binary coding or other coding methods, the '1's in the output code increases as the input voltage increases. e.g.

0V -> 00000
0.1V -> 00001
0.2V -> 00011
0.3V -> 00111 etc.

Its advantage is that glitches are reduced. However, to achieve binary coding as output, these thermometer coded has to be "encoded".

Hope it helps.
David.

digital thermometer adc codes

thermometer code : 0000-0001-0011-0111-1111

thermometer code encoding

A Flash ADC will give u a thermometer coded output... For a 3 bit Flash ADC, there are 2^3=8 levels... So outputs are
0000000,0000001,0000011,0000111,0001111,0011111,
0111111,11111111... (Notice that u have 2^N-1 bits for a 2^N ADC... These are converted to a 3-bit binary using priority encoding...

themometer code

with increasing the no of 1's serially, u will increase the current and hence there is no glitches compared to binary code where no of 1s increases at different places

thermometer code digital

it is used in dac also
