How to provide saturation current and temperature compensation in log-amp?
(a) Applying reference voltage alone to two different log-amps
(b) Applying input and reference voltage to same log-amps
(c) Applying input and reference voltage to separate log-amps
(d) None of the mentioned
The question was posed to me in an online interview.
I would like to ask this question from Log and Antilog Amplifier in section Operational Amplifier Applications of Linear Integrated Circuits
