login amp

A log amp must satisfy a transfer function of the form. VOUT = VY log(VIN/VX) Eq. 1 over some range of input values which may vary from 100:1 (40 dB) to over 1,000,000:1 (120 dB). With inputs very close to zero, log amps cease to behave logarithmically, and most then have a linear VIN/VOUT law. gengtoto com login
