WebAs the voltage is decreased to 4.9 V, only some of the least significant bits are cleared. The MSB will remain set until the input is one half the reference voltage, 2.5 V. The binary weights assigned to each bit, starting with the MSB, are 2.5, 1.25, 0.625, 0.3125, 0.15625, 0.078125, 0.0390625, 0.01953125, 0.009765625, 0.0048828125. Webthe total current is proportional to the output voltage of the amplifier. Since the currents sum together and go through Rf where the inverting input is 0V and Vout = IfRf. The input NMOS are proportional to the binary weights of the input bits. The lowest number of NMOS (R) corresponds to the lowest binary-weighted input (20 = 1).
