What is the relationship between the threshold voltage and the device's noise performance, particularly in terms of flicker noise and thermal noise?

The threshold voltage (Vth) of a MOS device plays a crucial role for its operation. At the same time, noise is an intrinsic factor. So how noise (flicker or thermal) change with the change in...

Can you please elaborate on the test methodology (rapid test) you are going to apply ?

Jukka Salminen

If you need to hemolyze the sample before analysis I would not call it a rapid test. Nowadays there are immunochomatographic tests that operate on whole blood. Or are you going to develop one?

Neha Yadav

To extract hemoglobin, add eight times the amount of water to RBCs and centrifuge. Take the supernatant containing hemoglobin.

Please find the links to papers that describe the hemoglobin extraction procedure straightforwardly.
