Problem 4.7(a): Assuming that the diodes in the circuit below are ideal, find the value of the labeled current in mA. Assume that VDD equals to 2, R1 equals to 1 kΩ, and R2 equals to 6 kΩ.
Problem 4.27(b): In the circuit shown below, D1 has 20 times the junction area of D2. What value of I2 in mA is needed to obtain a value for V of 51 mV if I1 is 6 mA?
