I need to measure 4-20mA current output from some sensors. How can i do that ? Currently i use resistive drop to get the analog voltage and provide that to ADC of the controller. Are their any current input ADC ?

You can use the 4-20mA R click from MikroElektronika which combines the current measurement circuits and also provides 16V supply for the loop. Best way is to use it on an Arduino Uno click shield.
4-20mA R Click - mikroBUS sized board which serves as a receiver in a 4-20mA current loop standard
Arduino Uno click shield - mikroBUS host sockets extension for Arduino Uno compatible boards
You can find here some tutorials on using the 4-20mA T (transmitter) and 4-20mA R (receiver) boards:
