Two teams are competing to design the interface circuit in Figure P3–83 so that the 25 mW 10% is delivered to the 1-kV load resistor. Their designs are shown in Figure P3–83.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%?
