A 4-bit unsigned binary DAC produces the following set of voltage levels, starting from code 0 and progressing through to code 15
The ideal DAC output at code 0 is 0 V and the ideal gain is equal to 400 mV/bit. Answer the following questions assuming an endpoint-to-endpoint line is used as a reference.
(a) Calculate the DAC's gain (volts per bit), gain error, offset and offset error.
(b) What is the LSB step size?
(c) Calculate the absolute error transfer curve for this DAC. Normalize the result to one LSB. (d) Is the DAC output monotonic?
(e) Compute the DNL curve for this DAC. Does this DAC pass a ±1/2 LSB specification for DNL?
