Two teams are competing to design the interface circuit in given Figure so that the 25 mW ± 10% is delivered to the 1-kΩ load resistor. Their designs are shown in given Figure.
Which solution is better considering the use of standard values, number of parts, and power required by the source? Would your choice be different if the power had to be within ± 5%?
