Find the output voltage of the log-amplifier
(a) VO = -(kT)×ln(Vi/Vref)
(b) VO = -(kT/q)×ln(Vi/Vref)
(c) VO = -(kT/q)×ln(Vref/Vi)
(d) VO = (kT/q)×ln(Vi/Vref)
The question was posed to me in semester exam.
The above asked question is from Log and Antilog Amplifier topic in section Operational Amplifier Applications of Linear Integrated Circuits
