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 ...

Unlike conventional logarithmic amplifiers, the proposed approach directly produces a current signal as a logarithmic function of the input current. The core of the proposed circuit is translinear ohm ...

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 ...
