What is the reverse saturated current of 1N914 diode,
according to data sheets it is constant , however according to caculations it also depends upon the value of 'R'
like,
Vo = kt/q * ln (vi/R*Is)
if we now arrange this equation for 'Is' the final equation is so weird :/ i want know what exactly the value of Is should i use for my calculations ???
i am designing simple Natural Logarithm Opamp in which diode is a feedback factor
