Figure QI shows the circuit diagram of a "Logarithmic Amplifier". In this circuit the feedback resistor of a normal inverting amplifier is replaced by a silicon diode. Since the current flowing through the diode increases exponentially with the voltage across the diode, the voltage across the diode will be proportional to the logarithm current flowing through it. Hence the output of the circuit is proportional to the logarithm of the input voltage. QI DI RIN Al Figure QI The current flowing through a diode is given by the Shock' y Diode Equat n: 1,=1, (e" =1) where , is the current flowing through the diode g is the charge on the electron (given at the back of the examination sheet) V, is the voltage across the diode K, is Boltzmann's constant (given at the back of the examination sheet) Tis room temperature (given at the back of the examination sheet) Given that /,> 1, an approximate expression for V, as a function of I, is Continued overleaf Page 2 of 9 QI (a) 0) Neglecting any input…
QI Ref RG RM A1 Vou VOUT Digital A DACI Input, DIN VDAC Figure QI Figure QI shows the circuit used to condition the output of the n- bit Digital to Analog Converter "DACI" having a digital input value of Dw. DACI may be assumed to have a voltage output with zero source resistance coded in "straight binary" such that • For a binary input of Dy = 000...000 the output voltage vaac is 0 V • For a binary input of Dw = 111..111 the output voltage vaac is Vn Where Vg is a positive voltage reference.
