(7)
Notice that in deriving Equation 7 no approximations have been made and there are no temperature-dependent
terms. The limitations are that the signal current not exceed I
D
/2 and that the diodes be biased with currents. In
practice, replacing the current sources with resistors will generate insignificant errors.
