Physics 536 - Assignment #8 - Due April 7th 1. Consider the following two current source circuits, in which VCC = 10 V and VEE = −10 V: VCC VCC I’C IC R’1 R1 R2 VEE R’2 RE VEE VEE R’E VEE (a) Derive the relationship between the values of R1 , R2 and RE that will produce a desired current IC in the circuit on the left. 0 (b) Derive the relationship between the values of R10 , R20 and RE that will produce a desired current IC0 on the right. (c) What is the advantage of using the circuit on the left when a load applied to the current source changes at a high frequency? (d) What is the advantage of using the circuit on the right when the current IC0 is constant but the temperature of the circuit changes? 2. Determine the values of the resistors R1 , R2 , R3 and R4 that will produce the linear relationship between the input and output voltages: Vout = a + bVin (1) in the following circuit: V CC R1 R3 R4 Vin Vout I0 R2 V EE As a constraint, suppose that the current used by the voltage divider between VCC and VEE specified to be I0 . 3. The relationship between the current, I, through the diode and the voltage drop, V , across it is I = I0 eeV /kT (2) when I À I0 . Determine the relation between Vout and Vin in the following logarithmic amplifier op-amp configuration: R Vin Vout 4. Determine the relation between Vout and Vin in the following exponential amplifier op-amp configuration: R Vin Vout 5. Describe qualitatively how to construct an circuit that produces an output voltage that is proportional to the product of two input voltages. Sketch the circuit configuration that would achieve this, but do not explicitly calculate any component values.
