A solid-state chemical sensor ion sensitive field effect transistor (ISFET) that operates in weak inversion and interfaces with negative current feedback to maximise linearity is proposed. The power consumption of this circuit when operating in the weak inversion region is in the nanowatt range, which makes it suitable for biomedical applications.
