how to do high side sensing

[kawaiicat]

i have think of using regulator but it have ripple. how can i do it..any other method

If you mean to sense high-side current, you may consider INA19x from TI ( **broken link removed** )

if you mean current high side sensisng, search EPN online, last month(oct, nov, dec) they had design idea for this stuff

Hello!

You have many IC's concerning this at Analog Devices, Maxim...

actually i have read about their products, but i don't know how they make it inside and the spec is not what i want, some need other voltage supply, some input voltage are pretty low
