Hi,

Could anyone let me know the functions of blocks circled. this is a analog sensor

 

Yes, it is entirely possible that "anyone" can explain those sections of the circuit. They appear to provide the needed functions to deliver a useful output from the sensor.

Hi Bill thank you for your quick response. yes it is an output of a sensor. but could you explain the functions of each circled block individually.

 

Your starter for ten: The top right box is a regulated power supply.

thank you. i think its a voltage regulator circuit as well. what about the other blocks?any idea

What do you think they are?

 

What do you think they are?

4 - a comparotor and 5- a current mirror or filters?am not sure!

 

Block 2 is a differential amplifier that also delivers a non-differential output. For block 3 yiou have excluded a number of parts that are important to the functioning of the system. That transistor T4, changes the gain at some selected switch point, while U1 and associated capacitors are functioning as some sort of comparator. Section 4 includes a dual voltage follower with added DC offset, and section 5 looks like it is probably a current output stage. Upon additional examination, section 3, including the transistor and diodes, might also be a voltage to frequency converter. I have not gone through a detailed evaluation of that part.

Hi,

Thank you so much for your time. very much appreciated.
