Recall that a function can be thought of as a machine which takes an input in (say x) and then depending on what that input is, it returns an output (say y) by some predefined rule (say f). The graph ...

This paper presents the design of a current-mode CMOS logarithmic amplifier, which by design is insensitive to ambient temperature variations. Its operational current ranges over 100fA - 100nA, which ...

Abstract: This paper presents the design of a programmable gain, temperature compensated, current-mode CMOS logarithmic amplifier that can be used for biomedical signal processing. Unlike conventional ...
