An integrated circuit requires two current sources: I1 = 1 mA and I2 = 1.5 mA. Assuming that only integer multiples of a unit bipolar transistor having IS = 3 x 10-16A can be placed in parallel, and only a single voltage source, VB, is available (Fig. 4.54), construct the required circuit with minimum number of unit transistors and determine VB.

How many bricks will need to build if gaps is neglected

A brick pathway of 4ft x 12ft has to be built. The standard brick size is 4 in x 6 in. How many bricks will you need to build it if the gaps between brick rows are neglected

Find zo of line

when the line was open-circuited, the measurement yielded an input impedance equivalent to a capacitor with capacitance of 40 pF. Find Zo of line, the phase velocity, and th
